Opus 5.5 one-shots a cyberpunk city with 800 craft and code-only soundtrack

A developer built an elaborate procedural cyberpunk city scene with Opus 5.5 and Three.js: thousands of towers, 800 flying craft, 64 holograms, and 16k raindrops.

The standout detail: even the soundtrack is code — zero audio files, with all audio synthesised live. The scripted arc (city dies, reactor wakes, grid ignites, breach returns) showcases how far one-shot code generation now goes.
