The Beta, or tbeta as it’s also called is a open source / cross platform program for video tracking and multi touch. It takes a video stream and sends out tracking and touch events. The program also communicate with software that handles the TUIO and OSC protocols.

On NUI Groups main page you could also find a link to a nice DIY multi-touch screen guide.
