The human brain is hardwired to recognize subtleties in faces. By not focusing on them directly your brain doesn't get the chance to translate them into faces, so instead you`re getting the `shape` version which looks far stranger because you`re consciously aware that it`s a recognizable face. Same thing`s going on with those `inverted-face` illusions that kind make sense until you turn them upside down. What you see is what your brain naturally interprets in a meaningful way, so the poo-eating grin of Tom Cruise looks fine on an inverted face, but suddenly doesn`t make sense in the greater perceptive context of a correctly oriented face. Incidentally, this is why it`s very hard NOT to look left or right. Your brain really REALLY wants to make sense of it.

@mantistador; as far as i can guess with my relitive low scientific knowledge is that there's a spot in your vision that your brain makes up colours for, this is where one of the nerves connect to where your eyes pick up an image. if you move closer to the pictures they don`t do this. so im guessing it`s just your brain making poo up because it liturally cannot see the whole face.
