"This is an absolutely magnificint time-waster! "Music" is produced by the positioning of the white squares in the matrix. Multiple squares in the same vertical colunm sound simultaneously like a chord. Timing is adjusted by moving squares sideways, as empty columns make no sound.
Sounds can easily be changed "on the fly" but I couldn't do that and hold the camera at the same time, just moving one or two squares can totaly change the "song".
