If you are not able to locate the slide carrier you are in a bit of a pickle.
For some reason, there seems to be more projectors than slide carriers around
(The carriers must have a habit of breaking or something) so the carriers are
not generally available alone.  Depending on your resourses and skills 
however you might be able to construct one.  Someone in the Chicago stereo
camera club would probably loan you a model.  Then again, for that matter,
someone in the club would probably be thrilled to go down and help with
a stereo slide show personally. (projector, glasses, stereo mounts, the
whole shee-bang)

You are right about the crossed polarizers.  They are mounted so they are
crossed in a \/ formation (which is standard for most all projectors and
glasses)

Good luck resurecting a classic!

Couldn't e-mail successfully so I'll post:

Reel 3-D Enterprises Inc., P.O. Box 2368, Culver City, CA 90231 is a good
source for books and supplies related to stereo photography and viewing.
Phone (213) 837-2368.  They sell copies of manuals for 3D cameras and
perhaps for projectors too.  They used to also recommend a few places
for repair of same.  The standard method for projection is indeed
two polarizers at with polarization directions at 90 degrees to each
other.  Viewers wear glasses with matching polarizers.  Reel 3D sells
the glasses.  You must use a silver screen to preserve polarization.
Reel 3D also sells slide mounts.  You will need to find out what
format of stereo slide mount your projector uses.

I have just set up two separate 35mm projectors to project separately
mounted stereo pairs.  I got unmounted polarizers and glasses from
Reel 3D (got them several years ago and got nothing since, so I don't
have their current catalog).

I've gotten several books from Reel 3D, some of which discuss
projection, as I noted in a post a few months ago:
"Photographing in 3-D" is  listed as their best book for the beginner;
includes 30 color stereo pairs suitable for free viewing.
"Stereo Photography" covers technical details on photography and viewing;
not a picture book.
"The world of 3-D" by J G Ferwerda is an extensive book on all aspects of
theory, photography, viewing, projection.
They have other books including stereo picture books, some View-Master
reels, etc.

I'll try to remember to look in them at home tonight and see which has
the best discussion of projection.

There is an annual convention for devotees of such stuff; I understand
it's THE place for used equipment, etc.  Unfortunately, you just missed
it.  It was in Fort Wayne, IN, a few weeks ago.  One of these years
I'm going to get to it!  I forget where it will be next year.

Please email me if I can provide more info.  Good stereo projection
(alas, I'm not in that category yet) is fantastic.  Your audience
will not forget it.  Best wishes.

Technology developed by the BBC makes the frame rate moot since a TV could
be fitted with their frame interpolation hardware which creates new frames
by tracking motion between two frames.  The interpolated frames have the
same resolution as the real frames.  Thus, a TV could have a very high
frame rate even when fed with low frame rate material.  Of course, you
could object to a TV that invents detail but may just get branded as a
digiphobe because of it :-)

Check back a few (40 or 50) messages and you'll see it mentioned.

It's been reviewed in a couple of the general photo mags as well as 3D
Magazin (A German stereo photography magazine).  I've only seen one picture
taken with it.  Apparently they took one of their good 70-210 zooms and put
in a set of filters (they swivel out of the optical path with a switch) in
so it takes anagraphic stereo pictures.  It works best when used at wide
apetures.
	Basically, it puts a blue filter on the left side of the optical path
and a red filter on the right side.  This way, light reflecting off an
object at different angles get coded with different colors.

If you have an old TLR (Or SLR with removable pentaprism) you can see basically
how it works.  Just look directly at the focusing screen.  If the lens is
a fast one (ie big wide optical path) you should see that the image on the
screen is in stereo.

I'm doing some research for my art thesis project and was wondering if 
there is any information on stereograms and the use as an alternative
for mind stimulation (ie:alternatives to drugs) to give effects of
'tripping' or other such sensations.  I know strobe lights and other
such things can cause interesting effects in the viewer but I figured
stereograms would be a much more interesting form of entertainment.
This may sound pretty stupid, so I appologize to those of you who think
it is...this is mearly an idea being researched for my senior thesis.
If anyone knows of any publications or articles that pertain to this sort
of thing, please email me with any information you can provide.

Thanks,

The quality of the stuff you are likely to see anytime soon is poor.  You
can pay about $1 per minute to use the "Virtuality" arcade equipment and get
some feel for cyberspace but that's nothing compared to the toys the military
has been using with their VR flight simulators for some time.  They even use
such exotic tricks as to track your eye movements and render the portions of
the scene in highest resolution (ie more triangles) which are directly in front
of your eyes.  As your eyes dart around, you get the illusion of a scene composed
of MILLIONS of triangles in real-time.

None of this has anything to do with the original subject of "stereogram drugs",
though I wouldn't be surprised it the military has also looked into dumping
graphics pipelines directly into the visual cortex and thereby bypassing display hardware altogether. ;-)
