What was the reason that the Kodak/Realist viewers had longer-than-ortho
lenses?  Was it to exaggerate depth a bit, or was it to lower cost
of lenses?  Seems that a higher-magnification "ortho" lens would be
ideal.

What lenses are used in those $500 milled aluminum viewers shown at
NSA '97?

A project like a custom lens, it seems to me, would
need quite a few participants.  To have quite a few participants, it
would require that quite a few people would have to be able to do
something with the lens.  In other words, when I get mine in the mail,
what do I do with them?  Custom make a viewer?  Replace lenses in
some viewer I have?  How many people would/could custom make a viewer to
put the lenses into?

>From a practical point of view, it would seem to me that replacement of
an existing viewer's lenses would be the most practical way to get the 
quanities up to a reasonable level.  Maybe get Dalia to sign up for
a number of the lenses to sell in modified viewers.

But probably not the $3 plastic reel-3d viewer.  :-)

So which common viewer has the largest diameter lens and sufficient
focus range to have a shorter lens work (or be modifiable)?

Might not a super-enhancement of this sort be more appropriate
for something like the AirEquipt Stereo Theatre (super lenses *and*
a multi-slide capability)?  Are enough of these around?

Enough questions for now, I think.  :-)
