TouchKit

Touch Kit is basically “a modular multitouch development kit with the aim to make multitouch readily available in an open source fashion.” Video after the break. Click here for one more picture.

The system must be hooked up to a separate computer, and also requires an external projector. As you can see in the video, there’s not exactly a whole lot it can do out of the box, but the open source platform can be tweaked by anyone with a little knowledge of C++.
