I've decided to collect some of my favorite projects I've seen people do with my Wiimote projects, derivatives of them, or distantly inspired (through the creator's own admissions). It's a surprise, and flattering to see how many people seem happy to credit me. Thanks all! The list gets more "unusual" the further you go down.
Two Wiimote Whiteboards to make a competative relay race:
Great IR wands for the Wiimote whiteboard. I've been meaning to make these, but I haven't gotten to it yet.
Some nice two handed, two finger pinching systems:
Wiimote Wheelchair art. Unfortunately, no video but more information at this link.
Head tracking prototypes with Anime assets. The effect of the girl coming out of the screen (about half way through the video) is very nicely done with the "haze" layer. His other videos are also worth checking out. I don't know what he does for a living, but he's good at it.
Wii Theremin gallantly created/performed by Ken Moore:
Finally, a video on "chicken head tracking". It doesn't use the Wii remote, but was posted as a response to my video and I love it!
