I feel obliged to point out the obvious, which is by no means directed at Tom
since I don't know what he means by left image vs. right image.

Stereoscopic images can be viewed by crossing the eyes.  They may also be
viewed with a steroscopic viewer.  The two (sub)images must be swapped to make
a proper stereoscopic image if you go from one method to the other.  Think
about it.

The eye-brain system being the wonderful thing that it is (I don't know where
I'd be without it), if you have the images backwards you still get the very
effective impression of depth.  However things are subtly wrong with the
perceived geometry.
