A mesmerizing real-time 3D pond built with Claude Opus 5.5 and Three.js. Rippling water physics respond dynamically to movement, koi fish glide beneath the surface, and cherry blossom petals drift across the scene. The lighting and reflections give it an almost painterly quality that's hard to believe came from a single AI-assisted build. Creator @buildwithsid dropped this to nearly 100k views in days — the crowd reaction says it all: "why is this soo pretty."
