October 30, 2006 Reactable is a collaborative, tabletop, modular synthesizer developed at the Universitat Pompeu Fabra in Barcelona. The team set out to develop an instrument that was intuitive enough for beginners to jump in without a manual, yet deep enough for musicians to use on stage. Ambitiously, they included the ability for multiple users to play the device simultaneously (both in person and remotely). The result just oozes the "I want one" factor, and has to be seen to be believed. The pictures simply cannot do this justice - check out the amazing videos of the device in use.
