I asked Claude build a physically accurate O'Neill cylinder you can walk around

Just a heads up - this site managed to choke WindowServer on MacOS 27/Safari long enough to trigger a watchdog reboot.

I never managed to load it and had to rush to kill its tab after the OS restarted and it began choking the machine again.

		Wow, I opened it on my workstation (high-end intel w/ 64GB RAM and a 5090 with 32GB VRAM) and it hung my Chrome. Oh- I see, was supposed to click something on the screen. Now it's running at 60FPS.

		Indeed, it also froze both Firefox and Chrome running on Arch with a Threadripper 9970X. Not sure what kind of hardware is able to run this webpage.

Takes forever to load, runs terribly and looks awful.

Not my experience at all.

		Motivated by this comment I decided to give it another shot, the tab crashed immediately upon clicking the "fly" button.

On iOS Safari:

Island Three could not start

Range consisting of offset and length are out of bounds

Reloading the page may help. A screenshot of this to @gruberbuilds on X helps fix it.

I’m not on X

The weirdest experience in this must be to never know if you're walking uphill or downhill.

		The further uphill you walk the easier it becomes as the apparent gravity decreases.

Anyone else getting this error on android chrome?

Where do the clouds come from? The AI?

They were in the original 1970's renderings too:

Given Earth-like gravity and Earth-like atmosphere, a sufficiently large structure will also have Earth-like clouds.

I can't use the site on my phone, can barely even read any of the text, so I don't know the text you're quoting.

If you are asking if clouds in such a structure are realistic, I'd expect so: clouds do form naturally in even much smaller spaces, e.g. one of the NASA buildings, I forget if it was the Saturn V or Space Shuttle assembly building or both.

		The Vertical Assembly Building was used for both the Apollo Program and the Space Shuttle, though it had much more ‘headroom’ for the latter. From what I’ve read the rumors of clouds forming inside of it are actually a myth, though there are condensation and airflow issues. I don’t have citations handy as it’s been a while (decade) since I’ve read this.

Over half the people can't run it right or at all. Why not share some representative walkthrough videos?

This is crazy Claude built this.

I saw the landing page and I was like, "no way, Claude built that in real-time? Incredible." And then it loaded and it looked like a videogame from the 1990s. Pretty impressive for AI to have built it , and for something like that to run in the browser, but it's so clunky and ugly that I couldn't try it for more than a few seconds.

I hate it when products promise something so breathtaking in posters or trailers that is utterly detached from how the products looks or works. I might have tried it longer had that landing page not set this high of an expectation.

Overselling a product may getting you a higher conversion rate up to a point, but it will only hurt you and crater the rest of the funnel.

		I suspect it needs a few tokens spent on optimization and clean-up.

Neat. I enjoyed the NPCs chatting about life onboard.

I've had an idea to build something similar - or more specifically, a game in this form, since I saw Eric Bruneton's Rendezvous With Rama video, now about 15 years ago.

Never did hand code it, even though I gained a lot of the skills and work in gamedev. This makes me feel time is running out to implement it with some of the unique twists I had in mind that become apparent with something like this ...

This is a website, not an O'Neill cylinder, and I can't walk around it.
