Roll a random hero, then paint over it by hand — pencil, fill, mirror and undo.
Generates back, side, run and jump poses from the active body as their own editable frames — switch between them with the tabs above the canvas and touch any of them up by hand, same tools as the front. Everything above the hips carries over as a whole when they're first generated; only the legs and arms actually move.
Experimental: an animated run cycle sampled at more points along the same leg/arm swing than the fixed run poses above.
