In Albert's GR there is no rotation - So drag here to play and get inspiration

▶ Live demo — runs in the browser, needs WebGPU (recent Chrome or Edge; Safari and Firefox with WebGPU enabled).

Every pair of fluid cells has an instantaneous center of rotation. Vortex Field is an interactive visualizer of where those centers pile up, side by side with the flow that produces them.

Field A — velocity. A 2D Navier–Stokes fluid. Hue is the direction of the flow, brightness its speed. Field B — rotation centers.
