Homebrew Multi-Touch Pad

This is my crappy version of those $10k touch screens that allow multiple inputs. The demo isn't very smooth due to the fact that my webcam can only pickup 15fps while using the correct resolution (it's definitely time for a new cam.) The software I used was TouchLib, and I followed several tutorials from Instructables.com.

Parts needed:
A webcam with high FPS.
A small to medium size box.
A piece of blank paper.
A sturdy piece of flat and clear material.
Scotch tape.
Soft, even, and non-directional lighting (make sure you have multiple light sources to prevent hard shadows.)

Here's one of the tutorials: http://www.instructables.com/id/How-to-Make-a-Cheap-Multitouch-Pad/

Here's where to get TouchLib: http://nuigroup.com/touchlib/downloads/

If you need any assistance with creating your own multi-touch pad, leave me a comment, or go to the forums on http://nuigroup.com/forums/viewforum/27/. If I have time and encouragement, I'll make a step-by-step tutorial on making your own pad.

Wrong, this PC was running Windows XP on an AMD X2 5600+ @ 2.8Ghz with 2GB of DDR2 RAM. Graphics were a GeForce 7600GT.
