$1,874 of Opus 5.5 tokens built an interactive 3D island from simple prompts

Developer @mdaman010 used Claude Code with Opus 5.5 to build a full interactive 3D island via natural-language prompts, spending about $1,874 in API tokens over roughly 2 hours across multiple subagents.
- Prompts were as simple as "add X and Y" and "this looks weird, make it better"
- The scene includes diving birds, burrowing crabs, fish swimming around a whale, wind-reactive cloth, and dynamic night lighting, built on three.js
- It runs at 60+ FPS at 1440p
- Bugs and artifacts remain, but it's a striking stress test of natural-language-driven 3D world building
