Three Easy Steps to Glasses-Free

One:
Understand how we normaly view objects/places/people.
Yes, people are not objects to be tampered with. But for this demonstration we've tampered with an old dude's eyes.

With normal vision, we see objects situated on our right on the right and the left on the left. Let's hope nobody is left out.
Normal vision stops us from bumping into things.
Two:
Force your eyes to reverse the normal process.

In order to see two flat images as a single 3D one, you have to fool mother nature into thinking you're only seeing one image from the combination of two flat images. In other words, you have to look at the picture on the right with your left eye and the one on the left with your right eye.
Right?

By performing this trick you should end up seeing three separate images where there once were two. The image in the center should blend naturally into a full stereoscopic view with all the levels of depth found in nature.
The most difficult part of this process is relaxing enough to make it happen. While it doesn't come naturally, with a little effort anybody can achieve the effect.
