This is exactly what I need instead of my whiteboard and pens that wear out.
This is a port of Johnny Chung Lee’s Whiteboard app for the actual Wii. Kudos & thanks to Johnny Lee, Team Twiizers, svpe, shagku and para.
To use this application, you need the following:
* A Wii with some method to run homebrew on it, e.g. the Twilight Hack
* Two Wiimotes. Wiimote 1 is for interaction, Wiimote 2 should be positioned somewhere where it can see your entire screen, but not much more. It shouldn’t be moved after you have started the calibration.
* An infrared Light Pen, very easily soldered according to this schematic.
