I ran across this on BoingBoing, where they showed the picture of the girl at right. Not a real girl, BTW — just a little photoshopping. The weird part is how this affects one’s perceptual system. When I look at those pictures (especially the girl, for some reason), I feel a bit like I’m cross-eyed, and no matter how long I stare at it, I don’t feel like I’ve actually clearly seeing the picture. It’s a very strange feeling, hard to put into words.

I speculate that the slightly alarming visual effects are caused by the special sensitivity of our perceptual system to human faces; that somehow these faces are “wrong” in a way that our perceptual system just cannot handle. Kind of like what happens when you get dizzy, because your perception (the combination of spatial and visual, in that case) is getting conflicting inputs.
