Neat! :D Minified JavaScript :( But from one Simon (canvas lover) to another I decided to chewing through the plastic bars of minification to see what was going on. In your loop you're doing: beginPath() arc() fill() You could get away with nothing but arc() and moveTo() in your loop instead and make it a bit more efficient on slower (mobile) devices, because only one new path has to get created. Your moveTo's x coordinate is going to need to be offset by the radius since thats where each starts. So it would look something like this: s.beginPath() loop start s.moveTo(10 * b + 5 + 4, 10 * c + 5) s.arc(10 * b + 5, 10 * c + 5, 4, 0, 2 * Math.PI, d) loop end s.fill() I didn't try out the code, just typing in the open air here, but it should work.
