Three.js developer Dan Greenheck built TideWater, a browser island with birds, crabs, whales, wind-swayed cloth, night lighting and a sailable boat, using Opus 5.5 and multiple subagents. The build used 59% of his weekly usage, and he later turned it into a fishing game. The dgreenheck/tidewater repo was created Sep 23 and had 528 stars by Sep 25. For builders it gives a real dollar figure for one person's day of agentic 3D work.
