 And behind Risa Davis is ... ME! :-)  (I'm the one pulling the cart ... in
3-d no less!)

I had no problem free-viewing this images ... but tell me, how hard is it to
registed the images for viewing with the old red/blue glasses of comic book
fame. Besides the cost of printing are there any other difficulties?

	I don't know what the added cost of printing red/blue
stereograms might be, but it is probably something like the price of a
colour page even though only two colours are needed.  I have always
found that red/blue stereograms degrade the images significantly.  It
works pretty well for drawing, diagrammes and comic books, but gets
irritating when a photograph has any degree of subtle shading, as
against high contrast.  I have seen photos presented in red/blue, but
have never tried to make one.

	One hint about their suitability is how quickly red/blue was
abandoned when the polaroid became available, both for slide projection
and for movies.  In my experience the best display is through a good
viewer made of optically correct glass, second is a plastic viewer,
third is free-viewing, next is polaroid projection and the last choice
is red/blue pairs.

	I'm glad you had no trouble with the pairs in _JW_.  They are
nearly the perfect size for people who don't have much experience with
free-viewing.  With a bit of practice you can also view pics about
double those printed there.  Anything much bigger than that requires you
to switch them for cross-eyed viewing.  Salvadore Dali even did a large
painting intended for cross-eyed viewing and Rene' Magritte also did
some stereo paintings in the same format.

	What we need now is an artist/juggler to design a stereo T-shirt
so that we could force people to cross their eyes whenever we walk
toward them. ...  Maybe Martin Frost could also concoct some two-hand
passing patterns for crossed eyes, kind of a Mills Mess for the
eyeballs.

	An now, back to reality.
