A fluid simulation that runs in the browser. Move the pointer, a finger, or your hand in front of the camera, and ink blooms through water in plumes and filaments. One self-contained HTML page: no build step, no framework, nothing to install.
Live at inkfall.voidstudio.top · made by Void Studio.
The water is a real simulation, not a video or a particle effect. Every frame the GPU solves the incompressible Navier–Stokes equations: the ink is carried by the flow, the flow curls into vortices, and heavy ink sinks while light ink rises.
