Well, you'd better make that exclamation, one more time!

Same with me George, but I don't think stereo projection is much
of a revelation due to the trade-offs such as dimmer and not as
sharp images. I am kinda surprised that you percieve the distances
as realistic! I have commented on this aspect before in a different
context. Even though the size is supposed to be the same as what
is portrayed, the convergence and accomodation is out of whack with
what reality would dictate. This I feel are major contributers IMO
to the images not being truly sensed as "being there". I am not
sure which is the greater of the two though. There is also the brain
cues, (other than how convergence and accomodation are interpreted by
the brain) that consciously know they are not really the size they
portray but I feel in this case it is not a significant factor.

As to the stereo window moving back and forth relative to the images,
again, I sense it as Paul does. That is for me it seems the stereo
window is fixed and doesn't move, but rather the scene moves back
and forth relative to the window. If the window is not held constant
then of course then I see the effect you describe.
