<I wonder if Bruce (or anyone else) can give an explanation for the
scaling effects of hyperstereos.  It has been said many times that
increasing the stereo base makes the image look proportionally smaller
and closer to the observer.  That does not seem intuitive since the
size of the image remains constant.  How can you explain and
demonstrate this to a beginner?>

Ray Zone responds:

If you refer to the lilliput or "puppet theatre" effect of hyperstereos
think of it in this way:

It is as if you have become a giant with eyes further apart in a (big) head
looking down upon the subject.  Because you have become larger in your
perception the world appears proportionately smaller.
