Just for fun: Face distortion

Matthew Thompson, an undergraduate at the University of Queensland, came across this illusion, subsequently dubbed the 'Flashed Face Distortion Effect'.  See if for yourself below.





Differences from the mean (slightly larger eyes, for example) become grotesquely exaggerated as the faces flash by.  If you pause the clip, you can see that there are no monsters in lineup, just regular people.
