@kbob@chaos.social each frame the polyhedron's projected edges are walked in steps, injecting dye (hue-shifted by depth) and velocity splats into a 32x32 fluid grid. The velocity comes from the difference between current and previous frame vertex positions, so the polyhedron's rotation naturally drives the fluid motion. Edges sweeping across the grid leave colored trails that swirl and dissipate.
