It's more opf a visual toy than a 'game' Lots of different effects to play with. You can turn off the live feed (so you don't see your own shadow / outline on the screen). It's kinda trippy. You have several modes to play with or just set it to RANDOM where you get about 3 minutes of each mode to play with before it moves onto the next mode.
It gets boring after a while though. It's still beter than the fishtank "aqua something" toy, which doesn't seem to do much at all.
