At university, more years ago than I hate to think about, I had a geology course. We had 3D maps and special glasses to view them. The instructor never bothered with the glasses. I learned from him you can view the pair in 3D by crossing your eyes. Works well, but can take a bit of practice to master. The old 3D from the late 19th and early 20th centuries is quite interesting.
My mother-in-law and step father-in-law (who is 86), just bought a new 47" flat screen. The salesman upsold them to 3D. They don't even have a BD player, much less a 3D BD player. Besides, my step father-in-law is blind in one eye. I didn't even go there.
