From the README

One self-contained HTML file: a real-time WebGL 2 fluid and a generative Web Audio score, wired to each other. The water you paint makes the music, and the music stirs the water.

inside a fragment shader, ping-ponged between two RGBA32F position textures. Their glow follows local water speed, so still water stays dark and moving water lights up.

feeds that energy back into splat force, bloom, drifters and mote brightness. The score genuinely conducts the sea, not a fake ambient loop.

a whirlpool that spins faster the longer you hold, a double click (or Space) calls a storm.
