Now the difficulty with ready-made periscopes is that the two mirrors are
about the same size.  For good stereo-splitter use, they would need to
have a "distal mirror" much larger than the "proximal mirror" (in the Eye
Stilt maker's useful nomenclature).  Actually, that would be a nice
feature in any regular periscope.

This suggests making a hyper-previewer.  You could use a single such
periscope with adjustable length - like a telescoping free-viewer's
assistant - to preview the effects of various hyperstereo bases when
setting up a shot.   A small hand-held version would be practical to
perhaps 5x normal stereobase, with moderately distant scenes.  "The
Hypershooter's Assistant."  Perhaps a larger, tripod-based set-up could
serve for more distant subjects -  two mirrors attached to two 'pods.

There need to be hyperscope rigs on many high outlooks - on tall building
observation decks, on scenic promontories at national parks.  There is a
hill in Kansas City overlooking downtown that would be ideal for a
temporary installation.  Anybody looking for an excuse for an NEA grant?
