2D optical illusions are dim-a-dozen. However, have you seen a moving 3D one before? Here’s one as seen on Maniac World.
Is the woman in the picture spinning in a clockwise or anti-clockwise direction?
very ugly ballet dancing
Whichever direction you see it spinning, try looking at the picture a bit longer – moving your eyes from the shadow to the black woman, and then back to the shadow again, continuously repeating the process.
After a short while… the direction will change! (At least it did for me)
Amazing hor? Anyone knows the trick behind this optical illusion?

Damn, I'm not even completely awake yet ask me to see ugly spinning ballerinas...
I don't think it's an optical illusion. The direction she is spinning in indeed changes after a while and you don't even notice it 'cos your eyes get bored and distracted and she changes direction just as you blink.
At least that's what I think. Any scientist here care to clarify if there is some phenomenon at work here?
it just quickly changed when both legs form up into one patch of shadow.
i cannot see the change!!! i've been staring at it for 15min and she's still spinning anti-clockwise. my sis saw the ballet dance change direction briefly but i still cannot see it.
and i've having a headache now... wahaha~
I agree with anti alvin that it does not change. But i think that it is oscillating back and forth so it can assume both directions.
Am not sure though. Anyone else cares to clarify?
OMG. i think i'm BLIND LA! i cant see it change!
It's actually not fake. The key is: you do not know if she is facing towards you or away from you so when she's moving from away to left she might as well has moved from towards to left, i.e. the illusion of change. The key is the lack of depth.
I figured this out after opening the gif in an edit program :).
Whoas I am impressed. But I actually still don't quite get you... what's the difference btw "moving from away to left" and "moved from towards to left"?
for those who cannot see , try to look at the line "After a short while… the direction will change! (At least it did for me)"...stare a bit longer and it will change directions.
I see it mostly spinning to the left, with the occasional sudden jerk back to the right ..
she spins on one leg, then she spins on the other. wake up, you dolts.
