Get a sort of effect.

I could never do those magic eye pictures, though my non-techie parents could, much to my irritation.

i think the key is to show Side-by-Side piccys rather than Above-Below. I tried tilting my head..too confusing, got nothing.

the photos should be side by side if you have your screen wide enough. try making your browser full size ?

if that doesn't work then i'll create another image with them both stuck together. let me know.

I've found a website that explains how to view these images:

i've just tried it with this image and had some success. It does kinda strain your eyes and'll probably give you headache if you do it for too long.
