Ok my last multi-touch post for a while. Jens Wunderling, a student of digital media class UDK Berlin, had also been creating a multi-touch surface for a community noticeboard project.

Jens began his project quite some time ago, but has had to put it on hold to complete other university work. The whole process has been documented on his blog, from buying the right cameras, hooking up the infrared LEDs and vision tracking software.

Whilst there are no examples of interaction techniques, the technology works and Jens has provided all Processing source code, Eyesweb and VVVV patches. If anyone else out there is working on multi-touch interaction, let me know.
