Look at it through your cell phone’s camera.  What a great tip!  8 more can be found at Wiimote Project.com.  I’m a little bit behind the curve on some of this stuff, but they’ve got great info on building IR pens for Wiimote interactive whiteboards and building them right.

Next week, Ivan and I present our progress at Ohio TESOL.  From there, one or both of us will be headed to TESOL and, if accepted, CALICO.  If you see us, come say, “Hi!”
