Hi,
I'm new here and If I first say heard about Johnny Lee's wiimote project from tllts irc chatroom. At the time I only had a vague interest but after recently watching his TED video I'm beginning to appreciate how the wiimote can be used to interact with the computer.
So far after visiting this site I have purchased a couple of IR pens from penteractive.us but I've yet to test them out with the wiimote.
Best wishes,
JR
