Hehe... now I can change the direction at will.

Blinking helps

Try doing it while you're staring at the head.

Mostly clockwise, with some concentration counter clockwise but it everytime she is at 3 or 9 o'clock my brain tries to make her change direction.

**Csargo** · 10-15-2007, 22:11

The picture switches back and forth. From Counter-clockwise to Clockwise. it's the pic.

Yeah, it's an illusion. It's easiest to get it to switch by looking at the feet. Cover up the rest of the body, then look and see which leg is passing "in front of" the other one. Then convince yourself that it's actually passing behind it.

NOW SHE'S DOING CARTWHEELS AMAZING!!!!

**RoadKill** · 10-15-2007, 22:36

okay, I've been staring at it for 10 minutes now, its driving me insane, I can only see it rotating CW.

**Whacker** · 10-15-2007, 22:36

I absolutely cannot see the clockwise rotation. I guess that's fine though, because I am definitely am left-brain dominant.

Edit - I just realized I posted wrong. Fixed.

Same...

I played around a bit in Corel Draw and erm maybe this helps in some way, I found the fast rotation a bit too fast...

The question is what can we gather from the shadow?
It's closer to her foot when it moves from the right to the left, to me that means the foot is further away and when it moves closer, the shadow is outside the picture, thus she would rotate counter clockwise.

**Dutch_guy** · 10-15-2007, 23:37

The trick is to concentrate fully on the little shadow at the bottom of the image, then you can see the counter clockwise movement.

**Charge** · 10-15-2007, 23:37

WTHell? She rotates in both CW & C CW! Just righ now I see it, then again cw...

**Blodrast** · 10-15-2007, 23:38

I can only see the counter-clockwise. I've seen it before, and I spent 2 minutes trying to see it the other way, but couldn't, and gave up (I'm lazy that way).
I admit I didn't try to focus on just one body part.

**Charge** · 10-15-2007, 23:53

I'm sure it rotate in two directions, changes them from time to time.

Thanks, Husar, you're a genius.
