NORTD have announced the latest version of their TouchKit DIY multitouch system, together with pricing. The system uses a plastic screen with embedded IR LEDs and a modified camera capable of recognising reflected IR light. Put together, with the included software, and you can create your own fledgling version of Microsoft's Surface multitouch table.

When a user's finger touches the screen, IR light is bounced out from within the plastic and recognised by the camera. The open-source software uses this light to interpret where contact is made, and controls the projector that creates the image.
The TouchKit full package costs $1,580 and includes the assembled screen (frameless, ready for your own choice of housing), embedded light strips, software, modified camera and full instructions/schematics/open-source. There's also the option to buy just the embedded light strips, one of the more tricky DIY aspects if you choose to build the whole thing from scratch, priced at $350.
