[photo-3d] Gabriel's post about the bi-lens viewer

This reminds me of the Sawyer's bi(something) slide viewer.
This was a viewer for viewing single 2x2 slides with a viewer.
The neat thing about this viewer is that you viewed the image
with both eyes instead of peering in with one eye. Supposedly
it was supposed to look 3-D. Funny thing is, it looked more
FLAT when viewed with two eyes! I speculate, years of
3-D conditioning has an opposite effect on stereophiles! ;-)

These things look like 3D viewers, but aren't. They were issued under
several manufacturer names. The viewers take a single 2x2 slide, are
illuminated and have a curved mirror to give you fake 3D from a 2D slide.
But if you find one, it's incredibly useful. You know that Mars in 3D set
of anaglyphs that Dalia and Reel 3D and others sell? (and there are
several other sets). Well you can take those bi-lens viewers, open them
up, take the cardboard glasses that came with the slides, cut out the red
and cyan filters (remember, blue goes on the right!) open the viewer
(clean it) tape the red and cyan filters behind the front lens elements,
and you'll have yourself the world's coolest illuminated 3D anaglyph 2x2
slide viewer.
