Claude Opus 5.5Video

One-file demoscene intro

Animation
Justin.md@JustinPerea

I asked Claude Opus 5.5 to make the most impressive demo of itself and gave it zero direction. ~5 hours and 697M tokens later, it made this demoscene intro. Every pixel and every sound comes from one 280 KB HTML file. No images, audio files, 3D models, or libraries. Sound on.
