The real trick to those 3d images is to be a bit walleyed, as I am. It seems to be a genetic trait- I had surgery to correct it when I was 13, my son had it at age ten, and in old photographs I can see that my grandfather and his great-uncle (a particularly successful mercenary captain by the name of Giuseppe Garibaldi) also had a "lazy" left eye.
Anyway, I can view old fashioned stereo pairs without a viewer- and stereo pictures were the first time I *ever* saw in 3d. It was a stunning experience. After the corrective surgery, I had much greater appreciation for the female form, too... depth perception is a wonderful thing.
