DIY Multi Touch table

I started a new project (well, I actually started it a long time ago and I'm now resuming it). It's a do-it-yourself multi touch table! Take a look at the following movie to get an idea of what a Multi Touch device is, it inspired me to build my own:



I'm building a table that uses FTIR and has a 80 cm x 60 cm screen, my test machine is running Ubuntu 8.10, Intel quadcore Q9550, 4 GB of RAM and a nVidia 9800GTX+ 512MB video card.

It'll be a challenge to get this working on Linux, as this hasn't been done/documented a lot before. Documenting my progress on Linux will be my gift back to the multi touch community that is out there!

When the table is finished, I also want to write software for it that makes use of multi touch (it's kind of boring to have a MT table with single touch programs on it!)
