Developer Dan Greenheck built TideWater, an interactive 3D island scene, in about 8 hours using Opus 5.5 with mostly simple prompts like 'add X' and 'make it better'. The scene features diving birds, burrowing crabs, fish swimming alongside a whale, wind effects, and dock lights at night. Cost: $1,874.40 worth of tokens — 59% of his weekly allowance on the Anthropic Max (20x) plan. Demo is live on GitHub Pages.
