This spinning lady was once popular on the internet as a way of a test to find out whether one is a left-brained or right-brained individual. The idea was, if you see the dancer turning counter-clockwise then you use more of the left side of your brain. If you see her turning clockwise, then you are a right-brained person. You can focus on the moving figure for a while and try to make the direction of her spin the other way around. Try it. What do you see, a girl spinning counter-clockwise or clockwise?

This video is nothing new but we have noticed the resurgence of this spinning girl among the social networks and the responses to this "test" are quite revealing, er.... at least some of them:

* "Wo-hooo! I can see the girl spin clockwise, then opposite. I'm a balanced person!"

* "The girl is programmed to spin clockwise, then counter-clockwise. It's a fake."

* "I'm a left-brained person through and through but why do I see the girl spinning clockwise?"

* "Please anyone, help! All I can see is a silhouette spinning clockwise!"

The truth is, it is simply an optical illusion (not a test) of how our visual system reconstruct the image (which is not actually "spinning" -- it's a series of 2-dimensional gif images animated in 34 frames). It is our brain's visual processing that interprets the video as a 3-D spinning image. You can actually force your visual system to perceive it as moving to the direction you wish it to by focusing on the shadow, or some other part.

Below are the differences between people with left and right brain functions:

While being logical and practical seem to be the more dependable choice than being "subjective" the right-brain dominant person's creativity and daring are equally appealing. For a "real" test to see whether you are a right-brained or left-brained person, check out this link or this one .
