Six modes
Ink, silk, smoke, oil, watercolour and pollen. Each changes several properties of the fluid at once, from heavy oil to light smoke.

Inkfall
Control without a mouse: your hand in front of the camera, and your voice.
Inkfall shows water with ink blooming through it. Every frame the GPU solves the equations of fluid motion again, and there is no pre-made video. The ink is carried by the flow, the flow curls into vortices, heavy ink sinks and light ink rises.
How it works
Hand control
Gestures in front of the camera: a pinch paints, an open palm stirs the water, a held fist clears it. The camera image is processed on the device and never uploaded.
Voice and music
With the microphone on, sound drives the brush: the louder it gets, the faster it moves and the more ink it lays.
Photo and video
A still is saved as PNG and video is recorded at up to 4K. The interface never appears in the recording.
One file
The whole piece is a single HTML page with no build step and no framework. There is nothing to install.
Built with: WebGL2 · GLSL · MediaPipe · Web Audio
