Just a minor point. Pulfrich movies do provide depth parallax in addition 
to the motion parallax. The slight delay in perception of the image by 
the darkened eye permits the simultaneous viewing for a split second of 
two adjacent video frames, which at 30 frames per second and a camera 
traversing speed of about 4 mph approximate an interoccular distance of 
2.5 inches thus giving the viewer normal depth parallax.

I thought I would pass this tidbit along since I spent so much time 
researching the subject in preparation for the filming of my hour long 
100% Pulfrich video, "A Walk Through the Roses of Reynolda Gardens in 
3-D."
