I don't have 3D drawing tools, but it's not too difficult to visualize the motion.
Matthew, please make comments/corrections to my crude drawing. The red/yellow planes merge/unmerge, and rotate together throughout the swing, but always stay in the plane of the left wristock motion.
In the golfers model, there isn't any useful relation to the inclined plane because of the variance of motion in the left arm. I'm still waiting for that ah ha moment though.
