No!

I made three variations two triangular kaleidoscopes side by side viewing
objects at a distance (Teleidoscope) so that both would have the same view
apart from the stereo differences. A large otherwise conventional
kaleidoscope that both eyes could look into which could be used as either a
teleidoscope or with objects in it. The third was like the first but
without the partition between the two kaleidoscopes, this could be squeezed
to vary the angle and so vary the number of segments in the view. In the
squeezed position the two operated independantly of each other but recieved
the same  view of close objects.
The problem seems to be that the reflection that produces the symetry means
that the stereo pairs are mirror images of each other and so cannot be
fused.
Yet there are the examples in  "Kaleidoscope Renaissance" and the one
mentioned in the original posting. Also a little while back on this group
sombody refered to a website for a 3D kaleidoscope which also used "Black
Light" which I understand to be UV. They were suggesting it might be used
for parts for stereo projects, I cheked the site and the device shown had a
hood like a Holmes viewer  there was a view reproduced but it did not apear
to be a stereo pair.
