emollick built BRUT, a complete brutalist city builder, with a single long prompt and open-sourced it on GitHub (playable at brut-city.netlify.app).
- 12 parametric building types, tunable by hand or inspector
- Sun, wind, weather, daily-life and aging simulation modes; 7 render views, 6 first-person modes
- Pure static site, no build step, three.js r180; run with any static server
A striking example of one prompt producing a fully playable, architecturally complete app.
