Hello all my name's Greg Smith out of Austin Texas, brand new to the world of wiimote tinkering. My interest with the wiimote is possibly using it as a camera motion capture device for use in visual effects. Should be interesting.

Welcome to Wiimoteproject!

That does sound very interesting but for motion capture you will most likely need to use reflective tape or use the wiimote as the moving device.

I hope you find the information and help you are looking for.

Possibly, the idea that I am inspired by is the same method that Sony uses for much of there camera animation for movies like "Surf's Up" and "Cloudy with a chance of Meatballs". They have a IR camera mounted at the top of a physical camera that the camera operator would use to film the CG scene. On the ceiling are several markers laid out in a non-repeating pattern (e.g. like the optical track balls). The camera reads this information and figures out the camera's position relative to the markers, as well as its orientation. With Sony Imagework's system, they then drive the virtual camera in their animation software and feed the output through the viewfinder of the physical camera that the camera operator uses, filming the CG scene like you would a live action scene.

What would interest, me is that this same technology could be used on a green screen shoot where with the assistance of a real-time keyer system (software and hardware that removes the green background) a "virtual set" could be composited in real-time with the green screen footage. This would give the director a better idea of what the shot will look like as opposed to actors performing on a green background.  Also if the precision of the wiimote is accurate, the data can be captured and used later during post production to animate the camera in the animation software.

Thats the idea at least that has my interest.
