Below is a century-old stereoscopic image, that is, two photos taken with a stereoscopic camera which is basically two cameras siting side by side, which produce two slightly different photos of the same target.

Now what you do is this....cross your eyes until you see three images, then focus on the central image and you will see the 3D effect.



Technology will indeed get us to true 3D viewing at some point and I assure you, we will like it!
