But the Realist format is five perforations per frame, not
the eight of standard 35mm photography. This frame size
yields 28 stereo pairs on a 36 exposure roll of film.

No, but a stereo projector, with opposing Polaroid
filters projecting on a silvered lenticular screen
produces a striking effect viewed with the kind of
Polaroid glasses used for 3D movies. My projector
is made by the long-defunct TDC company.

Not on standard monitors, but there are monitors with
a lenticular screen as used on 3D postcards and "tilt
to see moving image" postcards (one vertical, the other
horizontal that can display stereo images without
glasses. There are also other technologies, such as
spinning LED displays, that can dispay what appear to
be solid images in three dimensions.
