Claude Opus 5.5 generates a ~134KB realtime city demo, dubbed 'grand theft code'

Developer gandamuml showed off a 134KB realtime city demo generated by Claude Opus 5.5, cheekily named "grand theft code", noting much of it looks like RL-generated code with humans as just the bootstrap.
Replying, BuffMcBigHuge wondered whether such builds could be done piecewise: separate agents handling car dynamics, suspension, crumple zones, procedural buildings, global lighting, traffic, etc., then assembled together — a glimpse of both frontier model coding power and multi-agent decomposition ideas.
