Sometimes the puzzles are in an up-down orientation. Short of getting
out the View-Magic viewer, just rotate the puzzle 90 degrees. This
way the images are again side-by-side, albeit sideways!

At the 1996 Rochester NSA convention, Bill Ewald (retired from
Kodak and known as Mr.Stereo!) said, that while he worked there,
he used to fool them by have them move anything (even just a 
fraction of an inch) in his office and he would come back and
tell them what they moved. I don't remember the exact details
but I think he took a picture before and maybe after, then
freeviewing them he would quickly spot the displaced object.
I imagine he didn't do this in front of his colleagues.

Nope, not this time! BUT, I do remember it being discussed briefly.
I don't remember who brought it up (Bill Davis?). Dr.T!?! I never 
would have thought! ;-)
