Very clever!  I hadn't heard of that precise technique before, but it reminds
me of a device that was sold in the 50's for projecting frame-splitter slides
with a single ordinary slide projector.  Each framesplitter pair is mounted in
a single ordinary 2x2 slide mount, and they're made to overlap on the screen
by bouncing the projector beam off a slightly-angled-mirror device and onto
the screen.  (I forget how the polarization was done--I suppose they might have
used big plastic polarizers after the mirror arrangement).
    The projection arrangement would presumably keystone, but maybe that could
be corrected if the pairs were _also_ shot with a mirror device!  (I'm too lazy
to work out the geometry just now).
