Have you ever seen a synth and said "Man, what this needs is cartoon eyes?" A bit similar to the Buchla Box or theremin in that they don't have a keyboard to control the sounds -- it's probably closest to the Booper, invented by The Weatherman from Negativland (or, well, Circuit Bending), the Thingamagoop is a photosynthesizer... which means it basically uses light sensors to generate sounds. The signal's run through a couple oscillators and, well, it comes out as somethin' that's pretty dang awesome. I'm on the fence on pickin' this one up. On one hand, it's a really neat toy that makes noise... on the other hand, um.... um.... I dunno. It's not made of candy?
