# Kaleidoscope

> Neon ink pulled into rings, stars, hearts and lattices, then let go into a mirrored fluid simulation that dances to a shared tab. A real-time WebGPU experiment by Luis Bizarro.

A stable-fluids simulation on the GPU, run only in the fundamental cell of a kaleidoscope fold and mirrored across the screen. In each of ten scenes (Iris, Delta, Cross, Lattice, Bloom, Star, Ripple, Spiral, Hive and Heart) a sea of ink is pulled onto a shape, held, then let go into fingers and curls, shaded as glowing neon with bloom. Play music and click "share system audio" (Chrome and Edge on desktop), then share the tab or screen with its audio: kicks burst the ink and flash the bloom, snares shift the colours and spin the ink, hats sparkle. Move the mouse to stir and hold to add ink (on a phone, drag to stir); scroll or pick a scene from the list to change scene. After Panoply's film Tide.
