Rotating figure - you can change the direction yourself!


 Which way is the dancer spinning? You can actually see her spinning in either direction.  If you've practiced the crossed and uncrossed techniques you can make it spin both clockwise and counterclockwise.  Actually if you converge your eyes seeing double you will see the two figures (if they have been rotating counterclockwise) go in a clockwise direction after a few seconds - then make the two figures into one and it should stay clockwise.  To get it to go counderclockwise you'l  need to diverge your eyes past the screen to see two figures - after a few seconds they should become counterclockwise - make the two figures into one and it should stay counterclockwise.  This may be a simple test to see if your natural eye position at relaxation is a divergent one (spins counterclockwise) or is a convergent one (spins clockwise).  By controlling your focusing (accommodation) and vergences (ability to bring your eyes in or have them point outward) you'll be able to change this figure at will.  Enjoy!


Although we have 5 major senses, most of the information from our surroundings comes from the eyes, making sight a very important part of our lives. The eye contains many rods and cones and they gather information and send it to the visual processing part of the brain, the information is sent via electric signals. Optical illusions can be caused by our brain expecting to see something, and processing the eye's signals in a way that creates something that makes sense on one hand, but on further looking begins to make less sense.
