<< I would encourage the various members of P3D, who are knowledgeable with
 optics theory (Bercovitz and Abrahams come to mind), to have a look at
 Dunkley's site, because the effect really is quite interesting.  (Ken, you
 will have to re-announce your URL, because I've lost track of it at the
 moment.)

Dear Boris, I appreciate your comments and hope that it will inspire 
other P3D members to try to detect the 3-DVG effect.  The truth is 
:not everyone sees it.  And clearly, your assessment of differental
chromatic aberration is the starting point for getting a handle on 
what one is observing.  

However, careful examination will show that differental chromatic 
aberration, a major component of the effect,  does not provide 
a suitable (complete) explanation.  I have attempted to do this
in my SPIE paper (Vol.1915 Stereoscopic Displays and 
Applications IV, 1993, p.132 - 140) but I will be the first to 
admit that it is not the last word.  My hope is that a grad 
student in vision science will take on the job as a doctoral 
thesis and write a more diffinative explanation.   

However, what you need to know is that no matter how good your
initial results were, it gets better by a conservative factor of two if you
use the advanced 3-DVG.  The advanced 3-DVG uses illocal frames 
(that make the picture appear life size) and variable diameter
pinholes (that provide increased depth sensation).  Basicially, it feels
like you are looking through a View Master with a narrower viewing
angle.
