Tracking multiple laser pointers @ 200Hz using the Wii remote

A couple of videos (vid1 and vid2) from sha433 demonstrate that if you are willing to crack open your Wii remote (you'll need a tri-wing screw driver) and take out the IR filter, the camera will track visible points of light, including laser pointers. That's pretty neat. Additionally, it has also been recently discovered by a few people that if you read the data directly off the camera chip using I2C, you can get 200 Hz tracking (vs 100Hz that you get over Bluetooth). It looks like there might be a latency hit, though, depending on how you get the data into your computer.

So, if you are willing to get a little down and dirty with the hardware, you can pull out quite a bit more capability! Good job Sha!
