I saw further down a post about 3 d photos, well here is one. No special camera required. any camera can do it, and no equipment is required to view it.
How to view. Cross your eyes and you will see 3 pictures, concentrate on the centre one and they will fuse into one picture, may take a little practice for some.
Let me know if you can see it or not.
3d pictures are not new, they have been around since the 1800shttp://i137.photobucket.com/albums/q207/4711b/FL10.jpg
