Developer gandamuml shared a 134KB realtime 3D city demo generated by Claude Opus 5.5, cheekily named "grand theft code", following questions about the size of a previous demo.

He notes much of it is RL-generated code — "humans are just the bootstrap." He admits the whole effort was petty: critics had called his earlier demo AI slop and not technically impressive, so he built this one and slapped a sarcastic name on it.
