Found this online via Twitter through LACOtweets. This is a tone matrix, something that André Michelle constructed using a simple sinewave synthesizer triggered by an ordinary 16-step sequencer for our enjoyment. Kind of like a zen garden with sound: you punch in squares which trigger pitches (on the D pentatonic scale) and create your own sound experience. Pressing the spacebar clears the pitches so you can start all over again.
