What is the explanation for this?

4. Explained on December 4, 2003 6:51 AM writes...

The picture is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it.

I printed the image with a color printer (hp photosmart) and the illusion of movement didn't work. Is this due to the difference between the projected light on the computer v. the reflected light on the paper or what?

6. kathi on March 23, 2004 5:21 PM writes...

Two friends and I are looking at this. I am the only one that does not see any movement. Why is that?

7. Jesica Thurman on March 26, 2004 6:36 PM writes...

Wow! That's really neat-o! Awesome how somebody knows how to do that kind of stuff!

Very strange! When I move my laptop around with this on-screen, or walk around with it, it keeps still. As soon as I keep it still, it moves. It's it or me. Really relative. Yin & yang-ee.

thats really cool. did u make that or find out how to make stuff like that at your brain waves job or what ever it is?

when u sleep and you dream about things, is it what the brain wants or just its imagination running?

i noticed that when the circle is cut off by the edge of the screen it does not move

14. dan on May 11, 2004 10:57 AM writes...

or if you closde one eye it will stop. left right brain activity?

Where is the illusion. I have searched the website and cannot find it. Could you email me. So I may veiw it. Thank you.

16. NuNu on May 19, 2004 7:36 PM writes...

Notice that the further away u r from the screen the less movement there is :)

I LOVE IT DO YOU HAVE ANY MORE. HOW IS THIS COMPOSED?

18. sarah hardie on May 26, 2004 4:22 PM writes...

When you focus on one "circle," that circle doesn't move, but everything else does. So, if you follow the circles around you never can actually watch it straight on.

19. Val on June 2, 2004 9:00 AM writes...

Unbelievable, it even worked when I printed it in black and white.

20. Kevin Russell on June 7, 2004 2:11 PM writes...

If you print it out in black & white, it will still give the illusion of movement

this is way cool!!!! but how did you do it? what is the HTML??? can i put it on my web site www.tony-rules.s5.com ???

23. Al Seckel on June 23, 2004 5:01 PM writes...

This is a perceptual drift illusion created by Japanese vision scientist Akiyoshi Kitaoka. He has created many of these illusions, which can be found in my two of my books of illusions. The illusion works best on the screen, because the luminance values can be tightly controled, whereas in the four-color printing process they cannot, and so the illusion is greatly diminished. Also, scale and resolution is another factor. The web image is at 72 dpi, and you need at least 300 dpi for proper printing quality, so printing off the net will not help matters especially in this type of illusion.

If you are interested in the science of opticial illusions, then check out my books on the topic, which are the most authorative. They can be found on my web site: http://neuro.caltech.edu/~seckel

My latest one contains a whole chapter on Kitaoka's work.

28. Lon on June 28, 2004 5:15 PM writes...

I believe that there are small muscles in the retina that are constantly moving the 'retinal image' in a slow figure eight motion. This is due to the fact that a rod or cone cell is only traceable once & has to be 'reset' for the next light impulse. Our brain compensates for this motion, but it can be seen by staring at a point and noticing that within your peripheral vision, all objects start a slow figure eight sweep. I think that with so many detailed circles in the image that this slow eye movement seems to animate the image

29. Jennifer Heiner on June 30, 2004 8:42 AM writes...

This is so cool! It is very interesting how your brain makes the picture move. I stood about 3 feet awaay and it did not move at all. That's interesting. It is so cool!

A friend just e-mailed this to me and that was really neat. I've read some of the comments and thats weird that some people don't see any movement. I saw it as soon as I looked at it.

Hallo David,

I experience the same at times, when I look at the drapes in my home, the vertical pleats seem to move, as if the drape is moving by a draught what is not so.
Please tell me why this is.
With regards,

Optical illusions such as this are so fascinating. Interesting to read some of the other comments people make.

Those who think it's stupid or doesn't work are obviously brain dead - JUST KIDDING , DON'T GET YOUR BOWELS IN AN UPROAR. Sheez, some people just have no sense of humor.

Personally I like the one who feel off the chair and needed the first aid box, now you have a great sense of humor.

It was fun, thanks for sharing ;)

you demonstrate the illusion of illusion. We are so much more than the illusion we think we are. We are trying to make illusion real in every possible way... Illusion uses space in our creative mind and this is how we experience lfe.

Our real work is to wake up and use our inner power to create love and expand it to all life. Happyness, greatness and beauty comes from finding love towards eachother for a unified world

These optical illusions are really something to see! I wanted a biiiiiggg colorful poster with that and hang it in the living room so that whenever I open my front door, anyone there can see it behind my back and get them distracted.. heh...

Even my husband saw it on my laptop and said, 'Cool!!'. lol...

I would guess that the refreshing lines on your video display accelerate the effectual movement. Is this correct?
