		<description>well, Morghus, it's gotta be me to explain then...
It's a shadow, only a silhouette, so that by looking at the woman our brain cannot really tell whether it is the front view or the one from behind, because the details (eyes, mouth and so on) are missing. Apart from that, the picture doesn't have a perspective, so that pairs of elements (arms, legs, nose/hair) keep their relative position in the horizontal pane, and that causes the ambiguity: you can tell yourself that she moves clockwise standing on the left foot (looking from above) or the other way around on the right foot (quasi from under the transparent floor), and it flips similarly to the http://en.wikipedia.org/wiki/Necker_cube .</description>

		<description>I thought "Uh.. righto. The point of this is to annoy me with another one of those 'Guess the nifty optical illusion! Wohooo!' which I can tell already", and was about to be annoyed. Then I saw your continued post XD
So great !

Oh, and someone needs to explain this http://avva.livejournal.com/1785818.html to me.</description>

		<description>Ah yes, it's a nifty one Anna. Links are good :) But it's not the best one I've seen, because there are so many variables that seem unreasonable. Why is she jumping up and down while spinning? And why can you only see a small part of her shadow? There are so many "stupid" things done with it to achieve the illusion, it loses some of it's magic. Cool nonetheless though :)

I'm glad you all enjoyed this silly attempt at a joke, was debating myself over whether or not to post it :)</description>

		<description>...aaaand here comes the typical Anna's comment with a related link:
Have you seen this nice illusion already: http://avva.livejournal.com/1785818.html ?
You can change the direction of the rotation from clockwise to counterclockwise (unfocusing and looking down at the shadow helps:)</description>

		<description>Ahhh, the good old Ebbinghaus illusion, so good to see it again :)
(I had a course in cognitive psychology about optical illusions, it is fascinating to learn about what happens in your brain while you are being so easily fooled by pictures...)</description>
