Joe,

There was a discussion a while back of a product that claimed to do this
but in fact just created a shifted copy of the whole image--such that it
appeared to be a flat image floating in front of or behind the screen.  In
other words, a ripoff.  I don't know if the one you saw was that product...

Contrariwise, I just read an article in Computer Graphics World about a
group of engineers who used a software package (I think it was called
"PhotoModeler"?) that allowed them to reconstruct 3-D models of Princess
Di's limo before & after the crash from a set of photos (& from the amount
of crumpling to deduce how fast it hit).  One could conceivably use a
program like this as a front-end for creating a stereo pair from a set of
non-stereo photos.  I imagine it's quite expensive, though, and I doubt it
could work from a single photo.
