A photorealistic, interactive mountain stream rendered entirely in Three.js — no assets, just code. The scene features crystal-clear water with light caustics dancing across the riverbed, moss-covered granite boulders, and a dense forest canopy overhead. A small waterfall feeds the pool in the background. The UI corner shows drag-to-rotate, pan, and zoom controls, making it fully explorable. Creator @hayashimon1 built it with Claude Opus 5.5, noting that visual effects once too complex to attempt now feel totally within reach.
