So last night, I was reading through a thread here. Many of you probably already know which thread I'm talking about...

Anyway, a very interesting offtopic mumbling started to permeate the conversation. At its centre was this way cool picture of a spinning silhouette of a woman, a ballerina or some such.

The idea was that you could determine which half of your brain dominated your thinking by assessing which way you saw the ballerina turning in the picture. For me, she was twirling clockwise and I thought to myself, how on earth could she ever be seen to go the other way? because shes turning clockwise and thats it! Anyway, I toyed around, decentralizing my vision off of her, concentrating etc. It was a very powerful moment of shock to me when I returned my focus to her and saw that she had changed the way she was turning to counterclockwise.

Then I had large troubles to convince myself she had been turning the other way around before. I wasted a good 20 minutes trying again to see her turn the other way around and was getting frustrated. Finally, I "got hold" of the picture, and I can now switch the way she turns without great difficulty.

In essence, this is one of those pictures that is "wrong", like you can't really make it out to be what it is supposed to be. Its a trick, but because the motion alluded to is so graceful, soft, ones mind just overwrites the parts missing to make the motion sequence complete. I find it very beautiful. When I spotted the details missing making the sequence incomplete and imperfect I got a very nasty headache... :D

heres the article (and the girl) and I tried to add just the girl to this post, below..

I first noticed this effect many years ago while waiting in an airport, looking out the window at a spinning radar tower that was at the other side of the airfield. I looked at it once, and it was spinning one way, then after a minute I glanced again and it was spinning the other way.

I studied it for a moment and was soon able to switch rotation with a blink. It was a fun distraction.

Since then I've seen the effect here and there. Sprinklers are fun.

Nope can't do it. Still turning clockwise to me.

AAAAArrrggghhh............

Now got her swinging back and forth instead of spinning around.

This can't be good for a person.

.....and now her legs move one way and her torso another.

think I stop looking at this before it shorts out my brain.

[mmasters]

Looking at the feet is the trick for me I can get her to change direction on every spin. The link I posted earlier shows how it works!

Blink quickly and imagine her rotating the other way

[Opies]

The key is to watch either her foot and its direct shadow, or her other foot and its appearing and disappearing shadow. Changing your focal point changes her direction quickly and easily.

None of it does anything for me. She always spins clockwise.

[BigTex]

She is turning clockwise and I'm just going to let her do that.

To me, this is an exercise in how to leave something alone.

[Novus]

Here is what it looks when I set the gif variable to run the picture backwards. It is some type of weird optical illusion.

[Kylon]

She's spinning clockwise for me.

This gives me an idea for an art project.

Conceptual art of the viewer. It changes to be more appealing depending on whose viewing it...

Hard to do, but potentially possible.

[BigTex]

$this->bbcode_second_pass_quote('Kylon', 'S')he's spinning clockwise for me.

That is just a small test of the way the brain works, spatial relationships is not the only thing the brain attempts to solve. If you want a more accurate picture there are plenty of tests on the web.

Here's one:right/left



Also, Aaron started a thread titled 'how do you think?' in the psychology forum where I brought up my experiences with the right/left brain functioning. I wish I had kept that test, it was long, but very accurate.
