I found this great digital whiteboard somebody designed, for illustration purposes which uses the mini IR Camera in every WiiMote and some software, plus you need to build a small IR pointer from an old pen. I built mine simply by wiring up an IR LED with resistor (about 80ohms), a small switch, and a 2xAA battery pack all stuffed into an old pen. All credit goes to Johnny Chung Lee of Carnegie Mellon HCI institute for this system. I just built an IR pointer and used his software and set up the hardware. See http://johnnylee.net for the full lowdown. P.S. Blame Windows Movie Maker for the glitch in titling about 43 seconds into the vid - it showed just fine in preview!
