Ow my brain. Alright, so check out this optical illusion:
( Click to see, but only if you've got some time on your hands and some headache pills handy. )
Is the figure spinning clockwise or anti-clockwise?
The correct answer is, apparently, both. It seems that most people, upon initially viewing it, get locked into seeing one direction or the other. Through concentration, however, its possible to jar your brain into "reversing" her spin. I will say that it took me a surprising while to get the flip to occur, and as of this posting I still can't do it consistently. There are a number of different tips and tricks available on the internet (focus on her foot, or on her outstretched hand, or view her with your peripheral vision, or try humming music or doing sums in your head) but honestly I think its just a question of training your brain.
Various websites and pop-media articles have attributed left-brain versus right-brain notions, depending upon which way you initially see her, but there doesn't seem to be any evidence to back that up, so I'm going to assume its garbage.
