I am currently trying to help a colleague construct one of these for her classroom use, but even though we haven’t completed it, there seems to be a lot of promise here. The idea is taking a standard projector, 2 wiimotes, and an infared pen to create a interactive whiteboard, similar to a SmartBoard. The video below gives some context to the idea, and click here for the software and pens.
