Yes! Trying to make something that other people want is a good way to take the joy out of a project, and it dulls the uniqueness that could the result something truly special.
Sums up my mother's sculptures, or my kids' drawings.
If it serves the artist, it served a purpose.
Personally, I have an aluminium laptop stand which makes the laptop dockable but which isn't portable or makes screen/keyboard usable (secure for cats though) and I have a portable, foldable, lightweight plastic one [1].
I also do not enjoy the idea of using the bottom of a laptop on concrete. The latter material isn't nice for scratches (and every time it is put or leaves concrete is a potential mark).
So in this case, I believe a second monitor (or larger primary one) plus a vertical laptop stand would fit in the shown office.
>I also do not enjoy the idea of using the bottom of a laptop on concrete. The latter material isn't nice for scratches (and every time it is put or leaves concrete is a potential mark).
You can get concrete pretty smooth. Look up what some people do with polished concrete floors. Epoxy is sometimes used on top as well. You can get it as shiny as a bowling alley, and smooth enough to slide around on in your socks.
I mean, maybe you should not? The desk does not pertain that idea either. Nor does the monitor frame or laptop frame. It also does not fit in dynamic desks which are common these days. To me, the concrete laptop stands out too much in the office picture compared to the desk.
I am reminded by Mathilde µP's 'stone age computer' [1] which gave people a terminal in summer 1993 (at HeU 93 hacker conference) at a time where terminal access was more sparse. It served a purpose and gave a real feel through interfacing, but not ergonomic.
My smartphones have leather cases (not fake leather, real) and this gets interesting results with regards to scratches, grease and other wear and tear. My laptop case has the same (again: not fake leather, real). I could keep the laptop in the case if I use a hub to connect it. The heat goes up, and peripherals can connect. Put that in a vertical case and it fits in the shown office environment. Another option could be a wooden case for the laptop; these exist.

Oh man... I've never worked with concrete, but I would love to make a desk stand that looked like a little montréal métro station. They're all rather brutalist, and have flat tops haha
yeah i really want to try and make something like this. I was thinking of getting some spraypaint and making it look like part of it had been tagged with graffiti. Maybe one edge is broken so it looks like something I just found. I don't have the faintest idea of architecture styles, just thinking what would look cool and contrast with polished, refined, technology like a macbook or something.
I wonder what the practical limit is on how thin and light you can make concrete for non-structural items? I can see someone selling concrete mugs on Etsy, for example. Maybe with clever use of fillers and thin walls you could have a version of this you could actually lift. It looks great, especially in contrast to a white IKEA-style office.

People who make concrete counter tops use a lot of fibreglass fillers to get them fairly thin but if you wanted it truly light weight you’d probably need to make it out of a dense foam and coat it with something that looks like concrete.
Concrete counter top mixes usually use either much smaller, or no aggregate and use more sand. The mixes resemble mortar more than concrete and they are typically a little harder and less forgiving to work with.
There are a range of rendering mixes that look pretty much like concrete, or at least mortar, that would do the job. In fact just rendering it entirely (base coat, plastic reinforcing mesh, top coat(s)) should give a concrete-ish look while keeping things fairly light.
oh wow that takes me back. I remember touring, i think it was Texas A&M, in HS and they showed off their "concrete canoe" to the group. This would have been in the late 1900s.. 1995 or around there.
There are a lot of additives to concrete - the industry is large and has put a lot of money into research over the decades. You can read many many books on the pros and cons of different options.
You could mix concrete with other materiais too. I worked as a lab assistant in a engineering lab for some time. Putting styrofoam into the mix would result in lighter concrete within acceptable levels of resistance (for low level buildings). You might be onto something

I used work on foundations for warehouses, huge concrete blocks as anchor points and this is exactly how we got the bubbles out, we had a huge metal vibrator they call them high-frequency concrete pokers.
At first I thought you were talking about an actual rotating fan, which would be an awesome addition to this. Just a small PC fan running at a very low RPM built into the side in a circular cutout, with that worn metal patina look.
This man poured concrete around a power strip, chemically aged copper with ammonia, rusted rebar with peroxide, faked a damaged cable for vibes, and vibrated out the air bubbles with a dildo. This is the most unhinged and delightful Show HN I've ever seen.
This is dope af. I love concrete (was just gifted a book about concrete buildings for my birthday last week). I see things like this and remind myself that I have free will.
It's not clear what the change is, whether it is curation by hand or some other metrics, but it's a positive change, the old Show HN was getting flooded, as recently discussed. ( Although I can't work out how to find that discussion. )
I suppose the main thing so far is https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu.... The hope is to be welcoming to new users while also nudging them toward the intended use of the site. I don't know how well this is going to work over time so your comment is encouraging!
Same method though. There's a plethora of vibrating things to choose from. I suppose you could mold a large silicone tentacle to put on a jackhammer, too, and use that to fish for bubbles in your cement soup. Call the tool what you want, you haven't changed the method.
The contrast between raw industrial material and polished tech is what makes it work. There's something satisfying about building things purely for yourself with no product roadmap attached, the "dildo for air bubbles" detail alone proves this wasn't designed by committee
A sudden desire to have a concrete monitor stand appears in my mind.
Practical considerations: I feel like simply adding some cork to the underside of most things would increase compatibility between plastic/alum and the hardness of concrete.
I've always wanted to build a computer like the iMac G4, with the half sphere, the arm and the monitor. In my street there was a pebble/rock (the size of a rugby ball, pretty smooth surface) laying around near a tree, and I thought of taking it with me as the base for this computer. It's beautiful stone. I should have grabbed it, because now it's gone.
But it required a lot of grinding and sanding to make it ready. I think pouring concrete is a better option for my idea.
I asked for a monitor stand at work, back in the day. No money! So I went to the loading dock, found a wooden pallet for the little AC units we installed in racks, put that on my desk. Voila - monitor stand.
Yes, Sam is probably just having a bit of fun here, but I think it's worth presenting brutalism correctly as it's often so misunderstood.
Concrete is simply the mass production medium of the time, many of the patterns and moulds used in Barbican for example feature pretty timber imprints, scalloping patterns, painstakingly pick-hammered textured panels, or pleasing swooping shapes.
Further there is always space for glass, brass, Terrazzo and lighting.
Sam's design does feel cold, unnatural and broken, definitely not what brutalist living is about.
> cold, unnatural and broken, definitely not what brutalist living is about.
This can often be the actual experience of it, though. Part of why it's so divisive. Personally I'm on the "looks great, wouldn't want to actually live there" side.
The Barbican is an example of how good it can be when properly maintained by a community. There are plenty of less prestigious examples where the community cheered their demolition.
My subjective appreciation of building materials depends essentially on how gracefully they age. I find that concrete does not age well... and dislike brutalism for this specific reason.
> Sam's design does feel cold, unnatural and broken, definitely not what brutalist living is about.
AFAICT Sam is in the UK, and that is most British people's lived experience of Brutalist architecture in the UK.
Outside of a few notable examples like the Barbican, many towns and cities in the UK were saddled with ugly concrete behemoths that were poorly designed and poorly maintained.
Many of us actually find it very frustrating when people lionize brutalist principles and talk about 'real' brutalism. If a movement is what it does, rather than what it says it aims to do, then brutalism is a movement that left Britain looking dull(er), grey(er), water-stained and with plenty of dark corners and weird spaces that smelled of piss and were havens for petty crime.
Sam's brutalist laptop stand is entirely representative of brutalism as it really played out in many places across the country.
Most brutalism was never intended to last. It was intended to be a quick/cheap answer to get people acceptable housing in the cities. Then they would build something nicer for people to live in as the economy gets richer. Which is why it so often is associated with decay these days - the structure still stands, but it has outlasted the expected lifespan.
There are burtalism structures that were intended to be beautiful and last. They do that well (well beauty is in the eye of the beholder), but the majority was quick and cheap above all else.
My understanding of brutalism is that it’s an extreme interpretation of “function over form”. The most brutalist laptop stand would be a cardboard box turned upside down, not a slightly impractical block of concrete carefully manufactured to evoke a certain aesthetic.
If you want to get a feel of what brutalist architecture is like up close, go to the Barbican in london if you can.
Its quite surreal. Very much in-your-face concrete exposure. Yet, to walk and experience it with your eyes is a study of contrasts: a giant, comparitively modern, greenhouse, has a glass roof open to the sky and yet many floors have no light or windows at all. And in the outdoor spaces, like the fountain/canal running through the complex the concrete will sort of be in the background and lets you focus on everything else: the water, the swans and the people around.
Juxtapose that to low hanging exposed concrete roofs and walls in closed passages could make one feel constrained/claustrophobic/yearning for light.
The Barbican is not a typical brutalist construction. The term brutalist refers to béton brut, which means raw concrete. I.e. you can see the shape of the wooden slats used as a cast. The concrete in the Barbican was finished by drilling to create a dappled pattern, which obliterated the shape of the slats.
There are also lots of post modern elements. For example, the columns of the girl’s school have pyramids at the top to resemble pencils.
The south bank has more buildings that are a purer expression of brutalism.
My laptop has little rubber feet, so it dosn't scratch on its underside. But yes, the piece is solid concrete, so you wouldn't want to bash anything fragile against it.
And yet that laptop stand is not even the slightest bit slanted, one of the crucial details. I could simply take a book and put the laptop on top of that, to get the same ergonomic features. I am aware that ergonomic use is not the main point, but it would certainly not have hurt to consider that angle at least a little bit.
Why would this matter? If you were typing on it, that would be helpful, but this is for a laptop that sits on the side, while the user types on a separate (and likely much better) keyboard.
I found your comment funny and I only realized this pun when I read my own comment after posting it. I hope you keep your humor, despite being downvoted. You are probably downvoted, because people think it doesn't add much to the topic, and not because it isn't funny. (I hope so, at least.)
Never mind placing it, bringing it to the place where it should be, er, placed might also be a challenge. Unless you can drive a forklift into your office...
I love it, although if you're not into urbex or didn't grow up with brutalist architecture (soviet union, east germany, even parts of Zurich downtown) I guess in that case you don't really have anything to tie it to and without that connection it just looks like a piece of junk.
I love concrete as a medium but that's got to be heavy af and I would manage to smack my elbow on it all the time as well as smash my coffee mug on it.
I don't like it, from a pure brutalistic view point this obviously doesn't make any sense, it isn't practical and it doesn't make any effort to create a shape that is esthetically pleasing. The urban decay is even more outrageous, the whole appeal of urban decay is that it is "real", it's the thinking about all of people that went through the same structure throughout the years. Of cause it doesn't mean you can't make art about or featuring urban decay, but you have to be smart about it.
Something that would be useful in my case is a monitor stand stand. Does anyone know why almost no current monitor can be raised so that the upper edge is at eye level? Is it due to incompetence among the current breed of designers? Quite a few of my colleges have a stack of books beneath the monitor stand.
Law suits / claims, I'd expect, as tall is unstable.
If I sell a Monitor With Really Tall Monitor Stand and then you lightly bump your desk and break your monitor, you might want a replacement and call my stand "an unstable PoS".
If I sell you a Monitor and you stack books under it and your monitor falls... well... dummy, tall stuff falls over. Time to buy a new monitor.
Try getting “Enterprise” monitors like Dell UltraSharp or HP EliteDisplay. Not they only come with better feet (height adjustable & pivoting), they are calibrated and have really good panels which you can stare at for hours without fatigue.
Monitor arms are cheap enough and better than a stand. Clamp the arm to an edge and you can put things under the monitor, plus put the monitor where you want it.
Whether this monitor stand was decayed through history or artificially makes no difference if he's compelled by the elements of decay that he's replicating. You can get angry over design philosophy or you can just appreciate that this man crafted something with a very unique aesthetic.
It’s unfortunate that brutalism has become synonymous with “crumbling concrete”. That was certainly not the intention of the brutalist architects, but rather a side effect of the poor quality of the (sometimes experimental) concrete mixtures. 21st century (neo-)brutalist buildings won’t suffer from this.
I hate the brutalism and would never have anything like that in my home, but I certainly admire the work. Great job. It is true art, even if not for me.
Should have stolen a broken piece of concrete off a street and repurpose it to be a laptop stand. At least that would be authentic, and contributing to urban decay at his location.
This is quite tasteless… a betrayal of brutalist honesty. And the dildo thing is plainly disgusting. Let’s all be gentlemen and keep that sort of thing off the Net.
The tool used in construction for releasing trapped air bubbles out of poured concrete is called a concrete vibrator (SFW if anyone cares to Google for it). A vibrating ... ahem, personal toy is actually rather a clever substitute for a small scale project like this.
I'm about 75% confident this content is AI generated. Just intuition , no tools used. And I'm assuming our audience is autistic enough to put in the effort to build this. Composition, shadows & lighting seems synthetic.
Kudos to the creativity and no offense to the author. Partly running off a-priori risk model for internet content.
Well, from the look of it, to touch the thing wrong must be its own punishment, which is brutalism indeed. It insists on itself far too loudly, though, in what I would call a pseudapocalypticist or "Falloutpunk" manner. Too bad. There's nothing much wrong with it for its own sake, other than the ergonomy, but it sticks out from its environment like a sore thumb, adding nothing of value save the demand its presence be flattered and celebrated for its own sake - you know what? I take it back; you've not only recapitulated the brutalist concept, but apotheosized it. Congratulations on a successful work! It must have been a blast to build, which is where the real joy always is to be found of course, and I look forward to seeing which school of design you satirize next.
(Did you really immure a power strip in cement? The MOVs in those are wearing items, you know, and can though rarely do fail short circuit...)
I guess "I poured some concrete into a mold and put a power outlet in it" wouldn't be as eye catching of a title.
This is one of those things where someone does something incredibly simple, but dresses it up in pretty language and even some totally irrelevant chemistry equations (because they r so smrt) to make it look like more than it is. Which LLM did you paste the equation from?
And of course those who also have no idea how anything is made are unbelievably impressed. You can tell by the amount of exclamation points in all of the toxically positive reactions. Good work in that respect!
But hey, I guess it's not another vibe coded project with an LLM writeup. Progress.
I have not done much with concrete, but I have made lots of things out of many other materials over the years, and in general I have found that making things - and making them come out the way you want them - is never as simple as it looks. "Reality has a surprising amount of detail", it was once wisely written:
Do I like it? No. Do I want one on my desk? Absolutely not. Do I think it's even brutalist? Not in the least.
But it's still a cool as hell project. People need to do more things just because they want to, and to hell with what anyone else thinks.
It's very liberating, crafting something for yourself with no intention of selling.
Yes! Trying to make something that other people want is a good way to take the joy out of a project, and it dulls the uniqueness that could the result something truly special.

There have been ships made of concrete.
https://en.wikipedia.org/wiki/Concrete_ship
I've read that adding a little bit of graphene can make concrete much stronger, lighter and easy to shape, so would allow for thinner objects.

Related: Anyone know where to get that kind of keyboard in the photo? Specifically, where the number pad and arrow keys are on the left?
I've been looking and looking, but the best I can find is using a narrow keyboard with a separate number-pad only keyboard on the left. I'm in the US.
(It's better for your right shoulder to keep the mouse closer to your body like in the picture.)
In the mechanical keyboard community, I've also heard this type of layout referred to as "southpaw"
The keyboard in the photo was bought from Amazon in the UK, as "Black Left-Handed Mechanical Keyboard".
I am indeed a right-handed user, which is why I want my mouse within reach on the right.

May be worth considering too, especially if you're looking for a good keyboard with eg magnetic switches vs shitty rubberdome

Felt a little silly doing the work, but to be fair it did get the bubbles out.
When I did a small concrete project at home, I was advised not to over do the vibrator.
if we give it a little more polish, colder/greyer tones and "newness," it would fit very nicely for a Control fan :)
EDIT: https://store.steampowered.com/app/870780/Control_Ultimate_E...
At first I thought you were talking about an actual rotating fan, which would be an awesome addition to this. Just a small PC fan running at a very low RPM built into the side in a circular cutout, with that worn metal patina look.
as a control fan, i agree. the art direction in that game is something else.
I was delighted to see that a sequel is coming: https://www.youtube.com/watch?v=RJTBoQhWaC0
The maze level on the original game has to be an all-time best level design.
> I was delighted to see that a sequel is coming
the sequel trailer got me into the first game, actually :)) and I'm already sold on these recursive pigeons. is it multiplicative resonance?
> all-time best level design
well, the only worthy contenders are DEATHLOOP and Dishonored 2 :>
but yeah, Remedy does deserve every award they got with Control
also fun little project i discovered randomly

similarly the first game got me into Alan Wake, and now onto Alan Wake II
oh, Direc- excuse me, Jesse! have you met esseJ?
yes! one of my absolute favourite moments is the synchronicity lab
My favorite video game of the universe.
This looks pretty funny paired with a sleek fancy MacBook though.
You need a proper Soviet-esque workstation of a laptop to sit on that concrete block - go get yourself a nice, chunky ThinkPad T530.
You know what has always needed a solid concrete foundation poured is the W700ds. https://www.youtube.com/watch?v=6glQCMpqH7M&t=58s
Thinkpad 765d
This man poured concrete around a power strip, chemically aged copper with ammonia, rusted rebar with peroxide, faked a damaged cable for vibes, and vibrated out the air bubbles with a dildo. This is the most unhinged and delightful Show HN I've ever seen.
It's an honour just to be nominated <3
Have your office's PAT test guys flagged those exposed mains cables yet? :)
This is dope af. I love concrete (was just gifted a book about concrete buildings for my birthday last week). I see things like this and remind myself that I have free will.
Thanks for the inspiration.
I'm not an art theorist but I think the decay makes it something other than brutalist IMO
@dang, I'm not sure what's changed with the Show HN lately, but it's been much more lovely to read. Thank you for whatever changes which were made.
I'm glad to hear you liked the post!
Looking at https://news.ycombinator.com/show , it's definitely no longer a raw feed of show HN: from /new.
It's not clear what the change is, whether it is curation by hand or some other metrics, but it's a positive change, the old Show HN was getting flooded, as recently discussed. ( Although I can't work out how to find that discussion. )
Huge and positive change from the old “Show HN: Another vibe coded filesystem that I won’t even use but it was done with an LLM!”
I suppose the main thing so far is https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu.... The hope is to be welcoming to new users while also nudging them toward the intended use of the site. I don't know how well this is going to work over time so your comment is encouraging!
Another anecdatum: it definitely seems better to me in the last few days.
Thanks again to you and tomhow for all your stellar work on keeping the site as close to its original intent as practical these days
I certainly haven't heard of that technique to get rid of bubbles in the cement.
They make industrial versions of the same specifically for concrete.
https://www.amazon.com/s?k=concrete+vibrator
Well now I'm going to make a dildo out of concrete and list it on Amazon just to fuck with builders.
Vibration? Thought it was pretty common.
The article does mention a very specific choice of vibration equipment.
Same method though. There's a plethora of vibrating things to choose from. I suppose you could mold a large silicone tentacle to put on a jackhammer, too, and use that to fish for bubbles in your cement soup. Call the tool what you want, you haven't changed the method.
Yes, I did feel a bit silly buying and using it, but to be fair it did get the bubbles out.
Are you guys all trying hard not to say the words dildo, satisfier, or sex toy? Why so? AFAIK it is neither a rude nor a prohibited word.
Nah, I was just being pedantic about the “method” of removing bubbles.
I've seen people use the same technique and tooling for resin pours.
If it works, it works
This is cool. It's not for everyone and probably very heavy.
But I love the hacker feel of it.
I would personally pay money not to have this thing.
It's wonderful and I love that someone else loves it. The care put into it is fantastic. Vive la différence.
(https://en.wiktionary.org/wiki/vive_la_diff%C3%A9rence for those who may not recognize that phrase.)
How much money are you willing to pay? If sufficient I won't commission one and have it sent to your house. @AnthonyDavidAdams on venmo!
Before I was scrolling down the web, I was thinking that this guy went to any construction site and just took any good looking rubbles.
It can't be a good idea to condition yourself to be comfortable around an exposed wire that's near to a real power socket.
It's soldered to the rebar, which is grounded through the actual power cable
fair point. gotta trust that everything is properly hooked up and won't shift.
you'll only know when you find out the hard way
The contrast between raw industrial material and polished tech is what makes it work. There's something satisfying about building things purely for yourself with no product roadmap attached, the "dildo for air bubbles" detail alone proves this wasn't designed by committee
https://en.wikipedia.org/wiki/Brutalist_architecture
A sudden desire to have a concrete monitor stand appears in my mind.
Practical considerations: I feel like simply adding some cork to the underside of most things would increase compatibility between plastic/alum and the hardness of concrete.
Nice!
I've always wanted to build a computer like the iMac G4, with the half sphere, the arm and the monitor. In my street there was a pebble/rock (the size of a rugby ball, pretty smooth surface) laying around near a tree, and I thought of taking it with me as the base for this computer. It's beautiful stone. I should have grabbed it, because now it's gone.
But it required a lot of grinding and sanding to make it ready. I think pouring concrete is a better option for my idea.
Thanks for the inspiration!
I asked for a monitor stand at work, back in the day. No money! So I went to the loading dock, found a wooden pallet for the little AC units we installed in racks, put that on my desk. Voila - monitor stand.
Isn't the ornamental 'urban decay' detail kinda the opposite of the utilitarian and functional style of brutalism?
Yes, Sam is probably just having a bit of fun here, but I think it's worth presenting brutalism correctly as it's often so misunderstood.
Concrete is simply the mass production medium of the time, many of the patterns and moulds used in Barbican for example feature pretty timber imprints, scalloping patterns, painstakingly pick-hammered textured panels, or pleasing swooping shapes.
Further there is always space for glass, brass, Terrazzo and lighting.
Sam's design does feel cold, unnatural and broken, definitely not what brutalist living is about.

> cold, unnatural and broken, definitely not what brutalist living is about.
This can often be the actual experience of it, though. Part of why it's so divisive. Personally I'm on the "looks great, wouldn't want to actually live there" side.
The Barbican is an example of how good it can be when properly maintained by a community. There are plenty of less prestigious examples where the community cheered their demolition.
My subjective appreciation of building materials depends essentially on how gracefully they age. I find that concrete does not age well... and dislike brutalism for this specific reason.
> Sam's design does feel cold, unnatural and broken, definitely not what brutalist living is about.
AFAICT Sam is in the UK, and that is most British people's lived experience of Brutalist architecture in the UK.
Outside of a few notable examples like the Barbican, many towns and cities in the UK were saddled with ugly concrete behemoths that were poorly designed and poorly maintained.
Many of us actually find it very frustrating when people lionize brutalist principles and talk about 'real' brutalism. If a movement is what it does, rather than what it says it aims to do, then brutalism is a movement that left Britain looking dull(er), grey(er), water-stained and with plenty of dark corners and weird spaces that smelled of piss and were havens for petty crime.
Sam's brutalist laptop stand is entirely representative of brutalism as it really played out in many places across the country.
Most brutalism was never intended to last. It was intended to be a quick/cheap answer to get people acceptable housing in the cities. Then they would build something nicer for people to live in as the economy gets richer. Which is why it so often is associated with decay these days - the structure still stands, but it has outlasted the expected lifespan.
There are burtalism structures that were intended to be beautiful and last. They do that well (well beauty is in the eye of the beholder), but the majority was quick and cheap above all else.
Yes I had the same thought.
Imo brutalism is monolithic and unyielding. This is opposite, with the sturdy concrete yielding into plant overgrowth and exposed rebar.
My understanding of brutalism is that it’s an extreme interpretation of “function over form”. The most brutalist laptop stand would be a cardboard box turned upside down, not a slightly impractical block of concrete carefully manufactured to evoke a certain aesthetic.
How much does it weigh?
If you want to get a feel of what brutalist architecture is like up close, go to the Barbican in london if you can.
Its quite surreal. Very much in-your-face concrete exposure. Yet, to walk and experience it with your eyes is a study of contrasts: a giant, comparitively modern, greenhouse, has a glass roof open to the sky and yet many floors have no light or windows at all. And in the outdoor spaces, like the fountain/canal running through the complex the concrete will sort of be in the background and lets you focus on everything else: the water, the swans and the people around.
Juxtapose that to low hanging exposed concrete roofs and walls in closed passages could make one feel constrained/claustrophobic/yearning for light.
The Barbican is not a typical brutalist construction. The term brutalist refers to béton brut, which means raw concrete. I.e. you can see the shape of the wooden slats used as a cast. The concrete in the Barbican was finished by drilling to create a dappled pattern, which obliterated the shape of the slats.
There are also lots of post modern elements. For example, the columns of the girl’s school have pyramids at the top to resemble pencils.
The south bank has more buildings that are a purer expression of brutalism.
If you find yourself in West London, also check out Brunel University, all of the older buildings are pure brutalism
The best thing about the South Bank is that you can look over the river and admire the North Bank.
Sure, but as someone who likes the aesthetic, the Barbican hits all the right spots for me.
This is beautiful. Definitely beats the minimalist "cardboard box" stand. Bravo. I wouldn't want to move it though.
Is that surface concrete? Will it scratch the laptop?
My laptop has little rubber feet, so it dosn't scratch on its underside. But yes, the piece is solid concrete, so you wouldn't want to bash anything fragile against it.
Woah, he actually built it. I thought he found it on the side of the road, or something.
Thanks for the inspiration! I'll ask my wife if I can start crafting something similar to put on my desktop. Let's see.
I love it! I just wish I could enlarge the photos! EDIT: ah, it works to right-click open image in new tab.
This is the kind of content that I come to HN for. Well done, OP. I love the product and inspiration.
Thank you!
And yet that laptop stand is not even the slightest bit slanted, one of the crucial details. I could simply take a book and put the laptop on top of that, to get the same ergonomic features. I am aware that ergonomic use is not the main point, but it would certainly not have hurt to consider that angle at least a little bit.
That would have destroyed the brutalist cred.
Use a random cement brick instead of a book, then.
No, gotta use concrete.
Why would this matter? If you were typing on it, that would be helpful, but this is for a laptop that sits on the side, while the user types on a separate (and likely much better) keyboard.
Haha, consider that angle. (I'll show myself out.)
I found your comment funny and I only realized this pun when I read my own comment after posting it. I hope you keep your humor, despite being downvoted. You are probably downvoted, because people think it doesn't add much to the topic, and not because it isn't funny. (I hope so, at least.)
There are some subtly weak desks out there, quite a few actually, where placing this on top could be brutal.
Next up: Brutalist desk
There are some subtly weak floors out there, where placing such a desk could be fatal.
The funny thing is that in the 21st century, concrete can be quite light.
Well, there were people that made light concrete on the 20th century too. But not it's accessible to anybody.
Never mind placing it, bringing it to the place where it should be, er, placed might also be a challenge. Unless you can drive a forklift into your office...
I took it to the office on a little trolley thing
I didn't mean the laptop stand, I meant the concrete desk one of the parent comments suggested...
how much does it weigh? it looks like maybe 20-30lbs
Turtles all the way down.
I've seen quite a few blog posts of "old door on breeze blocks", the canonical brutalist/abandoned warehouse desk.
https://www.youtube.com/watch?v=R_fFqBhLBcE
Next up: structural engineering assessment of my office floor
I 100% would not want this on my desk, but I absolutely love it!
Just the execution of making it is impressive. Have you worked in concrete before? Or were you just like youtubing it the whole way?
Cool project, but not brutalist
this is really cool, what a great Show HN. i will try to make one this weekend :)
Chalk it up to far too many hours in the Sci Li but I quite like this.
Looks awesome! I like raw concrete. Plays well with the tech around it.
Thank you!
The professionals actually use a tool that looks about like a big (BIG) vibrator, along with various other vibrating tools.
And while at it… Why not a concrete laptop case?
Or a hi-fi? [1] I’ve heard concrete is a popular material in the DIY speaker crowd for reducing resonance
[1] https://collections.vam.ac.uk/item/O1227026/concrete-stereo-...
This is so weird. I love it. Thanks for sharing!
To be balanced, the reaction needs only 2 molecules of water. Solid stand though.
For a larger piece, I used a massage gun and walked around the mold hitting the sides with it. Worked out
Literally just looks like some trash sitting on their desk. Well done if that's the goal?
I love it, although if you're not into urbex or didn't grow up with brutalist architecture (soviet union, east germany, even parts of Zurich downtown) I guess in that case you don't really have anything to tie it to and without that connection it just looks like a piece of junk.
Can't say I'm heavy into brutalist architecture and then sit on an Ikea chair
Really solid laptop stand!
Me when the contractors forget a bag of cement after their job
This is sick but sad that it has to live in that open office cubicle world :[
A really complicated way to scratch your shiny expensive Apple device
Looks like a rat hideout.
Also known as an inertial mass dampener for your sit-stand desk.
I appreciate++ the design except for the too-perfect rebar and the exposed wire directly _in_ the concrete. Pros would use a conduit methinks.
The conduit is a good idea. I'm working on a Raspberry Pi stand in leather and walnut right now. Think I'm going to incorporate that somehow
OK I thought this was a late April Fools until I kept scrolling.
post-apocalyptic vibes
Sure is! It was a lot of fun to make, and I think it ended up with a nice urban decay feel to it
Did they actually show the tools used to remove bubbles?
That got cropped out of all photos in the interest of taste and decency.
A pic of a post-apocalyptic cement vibrator (perhaps not the dildo kind) would definitely have fit the aesthetic
I read every comment. What HN can be at its best.
This is pretty cool. How much does this weigh?
love the brutalist vibe of this. concrete is such an underrated material for desk setups. It looks way more premium than the plastic xD
I don't like it but I like that you did it.
It's hideous.
Use a Keychron concrete keyboard with it .
Looks amazing, I love it. Nice work!
I imagine its good on heat disipation...
ok, it's stable (at least from the photos), but I would prefer a more lightweight approach
They'll never steal it gg
Honestly curious--does this project "need" rebar? Not a concrete, but seems like rebar would only be needed for larger constructions?
Missing some graffiti.
You just need to cover it with graffitis to fully depict the experience of the poor souls living in brutalist buildings.
The author mentions urban decay and dilapidation multiple times and very clearly worked that into the design here
That's one way to prevent people from taking your desk at work
I love this! The pure weight of it is amazing, and distinctly makes a statement. Its a fun concept one could play with if they were making their own!
I think a "clean" and "contemporary" version of this would look amazing as well:
Along the lines of: https://www.modustrialmaker.com/blog/2018/8/14/making-an-imp...

I'm waiting for the man to make a laptop case out of concrete. That will be truly brutalist!
I had to wheel the stand into the office on a trolley, I'm not making a laptop case lol
Such a heavy stand might serve as a nice heat sink too, I would think. Doesn't have fins, but it could radiate evenly, and not even get that hot.
We need to see a benchmark with a Macbook air during extended workload.
I love concrete as a medium but that's got to be heavy af and I would manage to smack my elbow on it all the time as well as smash my coffee mug on it.
Yeah, getting it into the office was non-trivial!
When I first look at this I think "hey it would be nicer if it wasn't falling apart", but you could argue that's kind of the point. Well done
Is it just me or can you all hear the sound of the metal/aluminum scratching against the concrete?
Loved the brutalist movie, this actually seems quite nice assthetically.
try playing Control then! that's your dream come true :) (well, maybe except the Hiss part)
It's too much concrete for me, but hey, not every day you see an original and unique piece like this!
love it! WHERE CAN I PUT MY MONEY?
Now I need to make a concrete laptop
looks like trash. congratulations man
work of art!
I love it. I also really really like the brutalist/derelict aesthetic, and I think this nails it. Well done.
I don't like it, from a pure brutalistic view point this obviously doesn't make any sense, it isn't practical and it doesn't make any effort to create a shape that is esthetically pleasing. The urban decay is even more outrageous, the whole appeal of urban decay is that it is "real", it's the thinking about all of people that went through the same structure throughout the years. Of cause it doesn't mean you can't make art about or featuring urban decay, but you have to be smart about it.
> this obviously doesn't make any sense
That's debatable, but it's a moot point; it's pastiche, so it doesn't have the same goals or motivations as the original.
https://en.wikipedia.org/wiki/Pastiche
Exactly. This is more like the pre-ripped jeans version of brutalism.
Something that would be useful in my case is a monitor stand stand. Does anyone know why almost no current monitor can be raised so that the upper edge is at eye level? Is it due to incompetence among the current breed of designers? Quite a few of my colleges have a stack of books beneath the monitor stand.
I bought this Hyper HyperStand some years ago:
https://techaeris.com/2020/11/01/hyperstand-review-solid-por...
It's perfect: nice looking, highly functional, beautifully designed, and collapsible.
$29.99.
Alas, discontinued.
Perhaps eBay?
Edit: I just found a tricked-out version on eBay here:
https://www.ebay.com/itm/226769239456?_skw=Hyper+HyperStand+...
Law suits / claims, I'd expect, as tall is unstable.
If I sell a Monitor With Really Tall Monitor Stand and then you lightly bump your desk and break your monitor, you might want a replacement and call my stand "an unstable PoS".
If I sell you a Monitor and you stack books under it and your monitor falls... well... dummy, tall stuff falls over. Time to buy a new monitor.
Isn't the manufacturer to blame if I get neck problems then?
Many monitor arms on gas struts have extended range and this is no problem. Ergotron was one of the first
Try getting “Enterprise” monitors like Dell UltraSharp or HP EliteDisplay. Not they only come with better feet (height adjustable & pivoting), they are calibrated and have really good panels which you can stare at for hours without fatigue.
Monitor arms are cheap enough and better than a stand. Clamp the arm to an edge and you can put things under the monitor, plus put the monitor where you want it.
Whether this monitor stand was decayed through history or artificially makes no difference if he's compelled by the elements of decay that he's replicating. You can get angry over design philosophy or you can just appreciate that this man crafted something with a very unique aesthetic.
It’s unfortunate that brutalism has become synonymous with “crumbling concrete”. That was certainly not the intention of the brutalist architects, but rather a side effect of the poor quality of the (sometimes experimental) concrete mixtures. 21st century (neo-)brutalist buildings won’t suffer from this.
I hate the brutalism and would never have anything like that in my home, but I certainly admire the work. Great job. It is true art, even if not for me.
The most obvious issue here is that there needs to be a mat on the top to avoid scratching the bottom of the laptop.
More Industrial interior design than brutalist architecture
Should have stolen a broken piece of concrete off a street and repurpose it to be a laptop stand. At least that would be authentic, and contributing to urban decay at his location.
Summarily ruined yet again by massive British sockets requiring removing 25% of the volume.
Brits build their homes around the sockets, not the other way around.
I've always loved this style of architecture. People think commie blocks are ugly but I've always appreciated their simple utilitarianism
I want to hate it. But I think I really love it.
crazy idea - but no thank you :)
This is quite tasteless… a betrayal of brutalist honesty. And the dildo thing is plainly disgusting. Let’s all be gentlemen and keep that sort of thing off the Net.
The tool used in construction for releasing trapped air bubbles out of poured concrete is called a concrete vibrator (SFW if anyone cares to Google for it). A vibrating ... ahem, personal toy is actually rather a clever substitute for a small scale project like this.
First day on the Internet huh?
my annoying ass coworker has one of these, he keeps trying to migrate us to raw sql and C

I'm about 75% confident this content is AI generated. Just intuition , no tools used. And I'm assuming our audience is autistic enough to put in the effort to build this. Composition, shadows & lighting seems synthetic.
Kudos to the creativity and no offense to the author. Partly running off a-priori risk model for internet content.
Curious to see if my prediction holds up.
Well, from the look of it, to touch the thing wrong must be its own punishment, which is brutalism indeed. It insists on itself far too loudly, though, in what I would call a pseudapocalypticist or "Falloutpunk" manner. Too bad. There's nothing much wrong with it for its own sake, other than the ergonomy, but it sticks out from its environment like a sore thumb, adding nothing of value save the demand its presence be flattered and celebrated for its own sake - you know what? I take it back; you've not only recapitulated the brutalist concept, but apotheosized it. Congratulations on a successful work! It must have been a blast to build, which is where the real joy always is to be found of course, and I look forward to seeing which school of design you satirize next.
(Did you really immure a power strip in cement? The MOVs in those are wearing items, you know, and can though rarely do fail short circuit...)
I guess "I poured some concrete into a mold and put a power outlet in it" wouldn't be as eye catching of a title.
This is one of those things where someone does something incredibly simple, but dresses it up in pretty language and even some totally irrelevant chemistry equations (because they r so smrt) to make it look like more than it is. Which LLM did you paste the equation from?
And of course those who also have no idea how anything is made are unbelievably impressed. You can tell by the amount of exclamation points in all of the toxically positive reactions. Good work in that respect!
But hey, I guess it's not another vibe coded project with an LLM writeup. Progress.
I have not done much with concrete, but I have made lots of things out of many other materials over the years, and in general I have found that making things - and making them come out the way you want them - is never as simple as it looks. "Reality has a surprising amount of detail", it was once wisely written:
http://johnsalvatier.org/blog/2017/reality-has-a-surprising-...
