Old version:
It's a confetti factory simulation! (This is shamelessly inspired by an old AfterDark screensaver that I recall.)
Hit 'Z' to open or close valves.
Hit 'X' to change direction of conveyors.
Try to get the confetti into the correctly colored out bin in order to advance to the next level. Mixed confetti will reduce your score because it's really hard to sort after the fact.
