NOR_/D's TouchKit is a modular multitouch development kit that aims to "make multitouch readily available in an open source fashion." If that sounds awfully familiar, you're probably thinking of its sister project Cubit
, both of which are hoping to get multitouch into the mainstream as quickly as humanly possible. The kit itself is composed of hardware and software aspects, and of course, source files are provided for poking, prodding and researching. Interested? It'll be $1,580 shipped with a "fully assembled, frameless 70- x 50-centimeter multitouch screen, a calibrated infra-red camera, and the full base software pack."
