Hi Jamie, To use a wii remote with the OSG I'd either write a custom CameraManipulator to do this integration and provide the appropriate view matrix (via the getInverseMatrix() method) or just directly set the viewer's Camera's ViewMatrix directly and not use a CameraManipulator at all. Either of these route would avoid the potential pitfall of your code modifying the CameraManipulator's matrix only for this to be over written by CameraManpulator's own update methods.
For the direction issue, this is likely an issue with either ordering of the transform you are setting up or the coordinate frame. I know nothing of the specific wii coordinate frame so can't comment specifically on this. Robert.
