spray-burst

From the author

Builds a WebGL fragment-shader effect that looks like a three-ink screenprint reprinting itself, cycling through six bold geometric drawings (a touring starburst, broken rings, sliding bars, fusing discs, a pinwheel and a halftone wave) with every edge a dithered spray fringe that re-rolls at 24 fps, and the pointer laying ink on heavier. Use when someone asks for a screenprint or risograph look, a sprayed or stippled edge, a dithered signed-distance shader, a hand-printed boil, or a looping poster animation in WebGL.
