To which Abram Klooswyk replied

As others explained, of course all is possible.
I would strongly recommand first to try the Over-Under system.
The first to propose this system is (to my knowledge) van Albada,
almost 100 years ago. (I would be happy to hear of erlier occurences).

To which I replied

I canot remember if it was earlier than this but in Lenny Liptons book "The
Foundations of the Stereoscopic Cinema" he reproduces some early patents
for stereoscopic Zoetropes . One variation of which apears to consist of an
over-under 360 degree panorama wrapped around the outside of the drum .This
is viewed with an over-under viewer( which uses mirrors much like the
modern view magic viewer )while the drum is rotated .
 To return to A Amundsons original post I think he may have also mentioned
lenticulars himself and this would seem to be a posibility or perhaps even
a multiplex hologram.

I cheked the information the inventor was Hymmen and it was British patent
No 24,804 of 1897 in addition to the above device which is fig 17 there is
what apears to be a double image anaglphic version on a 360 degree drum.
The viewer seems to be wearing a conventional pair of spectacles but they
would presumably be red green. Figure 16 shows the same device but with a
screen in front of it with two spy holes in it which would have held the
filters but the viewer also seems to be wearing a pair of spectacles. Fig
18 shows two people viewing either  side of a verticaly rotating pair of
drums or more likely two looped 360 degree views each rotating around four
rollers in a rectangle  to give to give moving panoramic but otherwise
conventional side by side stereo pairs. P.J.Homer
