What you want to look for is a dolly truck (or "track" if the dolly is 
on rails), so that the subject is stationary and the POV shifts 
horizontally something approaching the distance between your two 
eyeballs. It's shuffling, but at a much higher speed, so the possibility 
of the subject shifting position between frames is lessened.

The incompatibility between cartooning (animated or otherwise) and 
stereo is that for the most part it is plano. The difference in camera 
position will not ordinarily result in a differential between the left 
and right image pair in the way we "seeing around" the object, because 
there is no Z-axis information.

If the object were drawn and rendered in "3-D," that is with z-axis 
imaging and/or lighting rotation consistent with a change in POV, then I 
would think that a successful stereo pair would be possible...
