Ok, heres what you do.
Go Cross-eyed looking at this photo and you will see 3 images, line the middle image up and try and focus on it. since your eyes have never done anything like this before (as it has to use every single muscle in your eyes) it may take a minute or two to be able to focus on it.
The middle image should appear crystal clear and look 3d, as if you were standin infront of it
neat yeah? what do yas think?
oh and the further away from the monitor you are, the more depth effect you get
