Back in the late 1980s, I would sometimes amuse myself by running a microphone through a digital audio effects processor and twiddle the knobs to transform my voice in very weird ways while listening in headphones. It provided hours of mindbending entertainment. Ah, the good ol' daze. Léo Chéron's WebGL particles experiment, called "Sand Ghost," gives me a similar feeling but it's visual and uses a webcam. Freak yourself out.
