277K-Gate Computer — JS CPU, OS & Games
Matt Shumer
@mattshumer_ · 397.9K followersA fully functional computer built from scratch in the browser — 277,000 logic gates simulated in JavaScript, a custom operating system layered on top, and playable games running inside that OS. Matt Shumer asked Claude Opus 5.5 to build it, and the result isn't a mockup or a visual trick: it's a real working machine you can interact with. The sheer scale — from raw gates to a bootable OS to games — makes this one of the most ambitious single-model builds ever shared publicly.
- 277,000 logic gates simulated entirely in JavaScript, forming a real CPU architecture
- A custom OS boots on top of the gate-level hardware simulation
- Playable games run inside the OS, completing the full stack from silicon to software
“I asked Opus 5.5 to build a working computer from scratch. And holy fuck did it deliver. 277k logic gates in JS, an OS on top, and games on the OS. This isn't a mockup... it's a computer. Run it: https://somethingbig.ai/computer”
