Wow, I'm impressed. And you didn't even have to use the new SCSC
On-Line SIRTS Generator. I am looking forward to seeing more of your 
ascii stereo pics. :-)

>There are four different placement combinations for a stereo pair:

Actually I think there are more. How about, instead of inverting
the pairs or chips, flipping them also. You'll get another
4 combinations for a total of 8 different combinations.

Note:
I liked the letters you used for the W denoting window and it's such a
handy letter to invert (and flip)! I took the liberty of changing the
9 & 6 digit and replaced it with a q & b respectively because these
letters can also be flipped (or mirror image) to p & d
Or in other words.
(originally 9) q inverted is d, q flipped is p
(originally 6) b inverted is p, b flipped is d 

Thus if we introduce flipping into the discussion, the original 
example A: Ortho & Straight will yield E, F, G, and H. All having
the common factor of being mirror images of A, B, C, D as well
as the differences of ortho, pseudo, straight and inverted.

 G: Orhto & Straight             H: Ortho & Inverted

Now after all is said and done, more combinations are possible
if only ONE chip is inverted or flipped! Anyone else care to
take a turn? What is the defintion of that kind of stereo pair,
if it can be still called a stereo pair.  

P.S. I think all this explaining is really getting out of hand.
I really liked Robert Linnstaedt simple and to the point answer:
Because if you turn your whole self upside-down everything you
see (with your actual eyes) is upside-down, but not pseudostereo.

P.P.S. Talking about pseudo and such, got me thinking about 
a 3D image that I took recently that was ortho, pseudo, and 
hyper. Now how did I manage that?
