BPM Synced Emotion Generator
Click the screen to flash it white and change one element of the face. Click along to a beat to get the flash & face change happening in time with music. Every other snare, beat, hi-hat... YOU control how seizure inducing it will be. Best on a beamer in a dark room full of sweaty friends.
