Which way does the dancer turn for you?

[David]

I can only see it clockwise. I hope my left side starts working soon, as I need to finish my master's thesis next week.

Started counter-clockwise. Then I looked at the text for 1/10 of a second and it started turning the other way. And now I do not seem to able to reverse it again..

An oldie, but a goodie.

[PBI]

Gah, I can only see clockwise. I'm supposed to be a physicist!

[LittleGrizzly]

its only going clockwise now and i can't change it !!! this thing is confusing and annoying... in a confusing way...

[atheotes]

i saw it going clockwise first... read the text and the side and decide this is bs... as i dont fit the bill.... but after readjusting my focus saw it go anti clockwise... now i can get it to go either direction at will!!!

[Don Corleone]

I see it both ways as well.

I wonder if the correlation on how to see one or the other (without the hidden text trick Galain suggested) is accurate. Trying to concentrate on the angular rotation and it's velocity (change of position versus time) is a left brained activity, so focusing on the way she's spinning will usually make her go counter-clockwise. Reading the text or letting your mind drift about the aesthetic features of the dancer's silhouted figure are right-brain features and causes her to spin clockwise.

And for those of us with really powerful minds, we can force her to stop spinnging altogether!!! Just call me the amazing Kreskin...

For those of you who want to do it, peek in here. But I'm warning you, you had better have a bottle of Excedrin handy, as you're likely to get a nasty headache trying this.

Spoiler Alert, click show to read: 

A motion picture is simply a series of frames, or still pictures, sampled at a rate faster than the eye can process, which gives the illusion of motion. How fast your eye (and brain) process the data depends on the number of brain functions you're performing. Concentrate, really, really hard on the image. Look for the patterns in the turning, try to tune your mind to the sampling rate the picture is turning at, then force yourself to anticipate the picture turns. You really can do it, at least I can, but if you have an epiletic seizure, don't blame me. Make sure you don't have any other interrupts for your brain to process. Be in a quiet room, be relaxed, and force your mind to conentrate on nothing but the picture, and its perceived angular rotation.

Lol guys! Try this out, nevermind the dancer and just keep reading those description words from the list. For me then on certain words the girl starts spinning towards other direction and with some other words she turns to the other way, like if the words are associated with different parts of my brain. When im focusing at the dancer girl she keeps spinning clockwise. .

For the life of me, I cannot get that girl to turn clockwise. Apparently, the right side of my brain is on a holiday or something.

That it is ;)

[Craterus]

Clockwise but I can make it switch direction. I think it's easier to concentrate on the standing foot and watch that.
