Als Freund elektronischer Musik finde ich das mal echt abgefahren. Eine richtig fette GUI für einen Synthesizer!

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.
