Yes!  I could not view slides in anything else than a red
button viewer!

OK, but I hope he knows that anything that is moving between
the shots can be treated as a stereo pair.  Some people could
call it "quackery".   Treating displacements as stereoscopic 
deviations is a very interesting and useful application of 
stereoscopic imaging.  That's the basis of stereoscopic drawings.  
That's how stereoscopic imaging was introduced to the world!
