>> Yet those who have experienced the
effect have experienced something, and it feels like, looks like,
(quacks like?) stereo.  I believe it has something to do with the
sharpness of the scene, and with the way the mind processes sharp
edges of what the eye sees.

Sharpness is part of it, I am sure. However, I also think it is contrast as
well. I have several sample black and white prints, 8 x 10, that are not
tack sharp. If you look at them, however, they appear to be exceedingly
sharp. I do not think this is an optical illusion just interesting to see
how apparent sharpness can be seen.

Also consider this: If you go blind in one eye, you will have very little
problem getting around and negotiating 3D space. Memory has a lot to do
with it. Eventually, however, you will loose the sense of stereo depth and
it becomes more difficult.
