This week's “Coolest Instrument Ever”

This will be this week’s entry into the “Coolest Instrument Ever” contest. This is called a Reactable, and it makes music while you play with cool little toys on the interactive table. Think of it as a classic analog synthesizer made with really cool Tinkertoys:

The official description: The Reactable, is a multi-user electronic music instrument with a tabletop tangible user interface. Several simultaneous performers share complete control over the instrument by moving physical objects on a luminous table surface. By moving and relating these objects, representing components of a classic modular synthesizer, users can create complex and dynamic sonic topologies, with generators, filters and modulators, in a kind of tangible modular synthesizer or graspable flow-controlled programming language.This instrument is being developed by a team of digital luthiers at the Music Technology Group within the Universitat Pompeu Fabra in Barcelona, Spain.
