Yes, you can project on ANY surface but you still need a VERY SPECIALIZED
stereo projector.  If you are going to go with the anaglyph method, it
makes more sense to transfer the stereo pair to one anaglyph slide.  Then
you can use any projector and any screen.

BTW, I was conducted by a person who has anaglyph SEM images in the
computer and wants to project them using an overhead projector.  Trying to
make transparencies (using a color printer, I imagine) and projecting them
with the overhead projector did not work very well (I was not told why, I
suspect the colors did not transfer very well and the overhead projector
builds up contrast and spills out a lot of light)  I wonder if one of these
units that project directly the image of the computer screen, might have
worked better.  Has anyone tried it?
