Eye Spy

This illusion works if you or someone you know wears spectacles. Why not fool them into believing you have a 3D monitor, when of course, it's simply the effect of chromostereoscopy (chromatic aberration). Without glasses the 3D effect is tiny (though may be still noticable), but if you must see the effect for yourself, then you could always buy something like this (no, I'm not affiliated with them :)

Here's another example of a picture which uses this technique.
