Well, Boris made a slide pair of a studio scene including an anaglyphic 
phantogram. To view it properly in projection, you need to wear *both*
polarized glasses and anaglyph glasses, at which point the phantogram 
sort of fits in with the surrounding scene.

OK, not quite 4D, but interesting nevertheless.
