Just a bit of fun... :) Hold down mouse button, and move around. Press C to clear. *** UPDATE: added some controls (defaults give original) For background info, see this forum topic: http://scratch.mit.edu/discuss/topic/36005/ I quite liked the feel of the original (i.e. as linked in forum topic: http://openprocessing.org/sketch/143842 ), so decided to recreate it a bit more closely than drmcw's version. Also, since it's only circles, I thought it'd be worth trying with pen, rather than stamping. (That also avoids the "set color effect" blocks, which still cause black flashes on some machines, because of the sprite-drawing mechanism in the 'ex-beta' player.)
