I run The Render Guy on YouTube, where I ask "what if?" and make AI build things it probably shouldn't be able to:
operating systems from scratch, a phone OS, a TV OS, motion graphics in After Effects, and documentaries.
Lumen OS 2: a phone operating system written from scratch by Claude. It has its own compositor, the "Slab" design, its own DHCP/DNS/HTTP stack, an HTML/CSS browser, and a YouTube player. It runs in QEMU on Apple Silicon. 8,227 lines of C, 32/32 end-to-end tests passing.
The AI writes the code and I'm not allowed to touch it. Then I boot it, test it on camera, and try to break it.
💬 Got an idea for what the AI should build next? Leave it in the comments on the latest video.
