The reactable is a multi-user electro-acoustic music instrument with a tabletop tangible user interface. Several simultaneous performers share complete control over the instrument by moving physical artefacts on the table surface and constructing different audio topologies in a kind of tangible modular synthesizer or graspable flow-controlled programming language.
The music isn't anything to shout about but what an innovative concept! Like having a jam session on a white board. I think Vanessa and Kevin might be interested in this.
