The author shared part of the prompt.
110k rigid bodies in real time, in a browser tab. Grab anything, fire cannonballs. Built with Claude Opus 5.5: Augmented Vertex Block Descent (SIGGRAPH 2025, Giles, Diaz & Yuksel) in WebGPU with @threejs . It's a physics solver that stays stable with huge scenes and big mass ratios. Opus 5.5 even put together this whole demo reel video just from a single text prompt in Claude Code haha 🤯 Try it: https://three-avbd.vercel.app (recorded on an M4 Max, lighter scenes run fine on older computers or on mobile) Code's here, MIT licensed. Go build something with it, have fun breaking things: https://github.com/sbobyn/three-avbd #threejs #WebGPU
Explainers0:47Tried Opus 5.5 to explain the Mid-Autumn Festival 🌕
From ancient traditions to mooncakes and family reunions, I turned the story into a short animated video.
The message is simple: No matter how far apart we are, make time for the people we miss.
What do you think of the result?
Explainers0:35Asked claude Opus 5.5 to make an explainer on how a mechanical keyboard works.
It wrote the music in code, used real switch recordings as the beats, built the 3D in @threejs and timed every cut to the beat.
No stock footage. no editing app.
What a time to be alive!
