Wearing the Oculus Rift and a mic headset, the “player” makes a sustained sound that then reacts with the game, creating audio-inspired fractal imagery. Changing the pitch and volume of your voice affects what colors and shapes emerge. 

I could see this game being used for meditative purposes or for drug-induced joyrides. Either way, it is an interestingly psychedelic experience that shows off even more possibilities for Oculus Rift integration.
