Turn off all of the lights and don't move! Brit Leissler's Octopulse uses its "tonetacles" to detect movement and light, resulting in a lot of garbled squeaks and murmurs from its analogue synthesizer. If this is really all it takes to master music, then I might just have to dust off that old Casio keyboard I used to bang on and see if The Alien Noise Orchestra will let me open for them. Anyone going to come?
