Fluid

A stirred fluid simulation that paints the frame and drags the layers below it

This is an actual fluid simulation — the same solver behind those cursor-ink demos — running live under your stack. A stroke pushes velocity into a grid; the solver then works out where every bit of that flow has to go so the fluid doesn't compress, which is the step that turns a smear into a swirl: push here and an eddy opens next to it. The layers below get carried along that flow rather than nudged off their spot, so a shape stretches into a ribbon that curls back on itself, and the ink it drags along keeps folding into finer and finer filaments. It has memory — the frame you see is built on every frame before it — so unlike the rest of the stack it can't be made to loop seamlessly.
