Spinning-Silhouette-Optical-Illusio.gif

It's kind of hard to do but you can see this silhouette spinning in either direction if you concentrate.

ok whats the catch, its only spinning clockwise

It works for me when I look at only the feet or the shadows and it spins in one direction, and I look at the head and it spins the other direction.

i naturally see it counterclockwise but can also see it go clockwise sometimes. If you're on a laptop, turn the screen upside down in it will switch directions, or at least it does for me some of the time. It works, I think, by your mind filling in the form of the woman's body. When you "see" the woman's leg going "behind" her, it really isn't, you occipital cortex is filling in that image, however when your mind is seeing it going behind her, some people's mind see it as going in front of her.

ok i got it, i just looked away from the screen so i could only see it in peripheral vision, and then it had switched to the other direction
