🎨 Paper Marbling Tray: Comb Strokes, Advection and Print

Marbling studio physics: four inks float on the size, a comb or stylus drags the surface (a divergence-free flow), colour is advected and slightly diffused, and the pattern is printed to paper. Compare the GPU solver with analytic solutions.

⚙ Under the hood

Drop four inks on a marbling tray, drag a comb or stylus through them and watch the colour being advected and diffused by a divergence-free surface flow on the GPU, then print the pattern to paper. Checked against analytic solutions.
