I stumbled across a demo for the Reactable on YouTube. The reactable is a multi-user eletro-acoustic instrument that has a tangible tabetop interface developed by “Interactive Sonic Systems” team is working in the Music Technology Group at the Univeristat Pompeu Fabra in Barcelona Spain.

Objects of varying shapes are placed on a translucent table. A videocamera underneath the table images the objects, which represent musical entities that interact with one another. A projector projects dynamic images onto the table that allow the user to visualize the electro-acoustic interactions among the set pf objects. By moving, or rotating objects, their properties can be modified.
Here are links to their three demos:
