This actually works! I don't have a commercial interactive whiteboard, but I am able to get an infrared light pen and a Wii remote set up to use as a cheap substitute. I bought my infrared pen from this source: http://www.wiiteachers.com/ I prop my Wii remote up with a piece of cardboard. Tip: if you're not a tech wiz yourself, borrow a few minutes from your tech aide to help you figure out the software download and Wii calibration.
