Yes, this is a great demonstration stereoview!

Again, yes!  I have modified a few RBT mounts by removing
the edge in one of the two sides, to gain access to the
RBT pin bar.  I am then able to shift the pin bar while
the slide is projected.  I use the Brackett Dissolver
which gives me access to the slide (there is no way to
access the slide in a TDC projector).  I then sift the
pin bar while the slide is being projected, essentially
changing the stereo window during normal projection viewing.
I think this is an effective demonstration and I will be
happy to repeat it in the NSA convention in Rochester.
