To list a few alternative solutions: Noblex once made a prototype 
motorized film-feed for their 4x5" projector, 220 format film, 
endless loop....it's listed in their original brochure, but never 
made it into production. 
Having a 4x5" Leitz Diaskop myself, it's a very tempting idea....:))

'Sectional projection' (my terminology for multi-vision projection on 
a circular screen) is troubled by focussing on such a curved 
plane....so you need several projectors, each covering only a small 
angle.

For personal viewing, Discovery Channel once showed a stereo-camera 
plus viewer, using 70mm film, and where the viewer was put on a 
rotating base....the film simply moved through the viewer according 
to its angular orientation....that's as close to virtual reality you 
can get, and *without* any 'puters or electronics....
