I recall at the NSA convention in San Antonio years ago at one of the
theater showings that the presenter said that if he had people in an
audience who'd never seen stereo slides before, he had a little trick.

He'd have 3 copies of the same view. One would be just a normal flat
view (one eye). The second would be the same one image, but positioned
with a little displacement so it appeared to be behind the window - that
got oohs and ahhhs. Then he put the same slide up with both images and
it blew people right out of their seats (he said). 

The next time I'm in a position to do so, I'm going to try that..
