Have you considered taking the job of an astronomical blink comparator? ;-)
[for those not familiar, the comparator is a piece of equipment, not a
person].

I am thinking (low level) about buying a stereo camera.  Several
are available as well as viewers.
I suggest if you are really interested in stereo pairs, the book by Wanless
published by Hubbard (with the cheap stereo glasses) on aerial photographs.
You can feel like a bomber pilot. 8-)
As mentioned in a criticism on scientific visualization, I think the
best current work is being done by the biologists who's complexity problems
just grab an issue of science and keep your stereo glasses handy.

You can continue to take crude stereo, but if you get a collection
of slightly inconsistent base pairs, handling becomes a pain.

P.S. I just retrieved my books (about a dozen) on image processing for
remote sensing: Bernstein, Simonett and Lintz, Wolf, Castleman, Sabins, Swain,
etc.
