Opus 5.5 autonomously coded a fully procedural kaiju simulation in pure three.js over 3.5 hours

To test creativity, the author issued a deliberately minimal prompt: 'Build a fully procedural AAA quality kaiju simulation in three.js using pure TSL and modern techniques.' Opus 5.5 then worked autonomously for 3.5 hours, producing a kaiju simulation written entirely in pure three.js code. The full prompt and an interactive demo artifact are public — a striking data point on long-horizon autonomous coding and creative capability.
