Stereoscopy. Wikipedia defines stereoscopy as "Most stereoscopic methods present two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined in the brain to give the perception of 3D depth. This technique is distinguished from 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye movements."
Stereoscopy got very popular very fast. LOL, here is the first internet cafe, or, the first Google Glasses

I have a stereoptican (I think that's what it's called...) inherited from my grandmother packed away somewhere. I should get it out to show the kids. I used to really like playing with it. Thanks for the reminder! Great stuff on your other blog lately. Melissa S.
Hi Melissa,
Thanks! My grandparents had two built-in bookcases at the end of their parlor on either side of a fake log fireplace. Inside one of the bookcases was Harvard's great Books series, which I loved looking at the titles and the bindings, and a steropticon set of glasses and a whole set of cards to look at. I liked those when I was a child also. I wonder where it is now.
