The Laser Harp is a light-sensitive musical instrument. It is played by moving hands over laser light sources in order to send MIDI commands when a beam is interrupted. These commands can be sent to different electronic devices such as synthesizers, samplers, controllers and other.

That was cool. Took him a while to get to the coolest part with the actual “laser harp.” But when he did, it was totally cool.

yep, way too long on the build-up (even though that was itself pretty cool music). At about five minutes, I’d scrolled down here to whinge about the lack of the actual ‘harp’ — then read your comment and, just at that moment, the real action began. As you say, totally cool!
