you will probably need a middleman program to take the wii data and convert it into OSC messages so PD can read it.

just google " wii + OSC + your operating system" and you should find what you need.

OSCulator (mac) is good. and someone just said that 'glovepie' is good for windows.

then just map the pitch, roll and yaw of the wii remote to the camera angle.

but note that the acceleration sensors in the wii are better suited to more rigorous movement. for subtle movements, the infra-red sensor seems to be the way to go...but then you need an infrared emitter.
