Physiology & Medicine / How do people see the 'hollow mask' illusion?

What's really freaky about this illusion is that if you look at it upside down, you can see the inverted mask. Then if you rotate your screen after a few degrees it flips back into a face. But upside down, it looks SO unlike a face that you just can't see why you'd ever perceive it differently.
