Tallman you can see the 3D images, you just haven't yet. The first time I saw one those posters was in a mall, about 8 years ago. I stood there for about a half an hour before I finally saw it. Then I lost it and got again in about 10 seconds. I bought the d*** thing right then and there. The next year they were selling for a tenth of what I paid.

I can see all of the images at this site Ramon posted http://www.magiceye.com/3dfun/stwkdisp.shtml
some take a little while others less time. I can see the blip page quite easily.... more easily than those 3D images.

Good luck and don't stop trying.
