ARToolkit for processing tests from den ivanov on Vimeo.

Testing video of my ARToolkit library with multiple patterns handling. I used here rewritten version of SimpleARToolkit library from Bryan Chung and OBJLoader for handling OBJ 3D Models. Sorry for loud audio. Just mute it.

Testing MSA Fluids processing library on multitouch table. Looks great?

Our first multitouch bar table. I do all programming for this toy.

Just quick demo of processing multitouch. Nothing complicated, just for info what i'm still alive

The reactable, is a state-of-the-art 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.

Just check videos, this is really awesome. And most amazing part, it open-source (flash sources included)
