Thom Gilliam makes wonderful curved stereocards. He explained the procedure
in brief one evening at the Richmond NSA convention. I do not remember all
the details, but I believe it involved heat and a curved press of some sort.
The result is very pleasing. I own a copy of one of his full moon
stereoviews with the round pictures/chips on the curved card. It's among my
favorite cards. =)

Thom, are you still out there? Can you tell us more?
