What do you see? Perceptual test

Same here. I feel nauseous and have a headache, now. It's painful to look at that image.

To me, there's no rotations, but there is a lot of shimmering & flashing, and parts that disappear and reappear. I looked at it on my iPod screen though; if I don't barf first I'll try it with my desktop computer.

I agree about the nausea and headache feelings...I can't stare at it for long.

If I move my eyes around parts of the circles rotate, but most of them don't.

If I keep my eyes still, nothing moves.

Is it supposed to rotate even when you're staring at a black dot?

looks like rotating thingys to me

I see rotation as well.

I see an owl

OK, on my 23" monitor it is a little different. The circles seem to rotate a little bit one way and then back a little, over and over. They also seem to "breath" and warp, as if reflected by water with waves/ripples on it. Like wow, man.

It also nearly locks my brain up. Sort of a forcible, instant space-out.

Wow, sorry about all the unpleasant side effects for some of you. But thanks for your input.

I don't see them rotating. Just the different patterns when focusing on the whole image or each set of circles.

I'm not sure what it is supposed to do, but most people seem to see the rotation right off. I had to have it brought to my attention. Once I realized it rotated I also discovered that I could stop it from rotating when I kept my eyes still. Then I started to wonder what that meant about how I looked at it at first, when I did not percieve the rotation but was studying the image. I think I stared intently at one spot and then another and was not letting my eyes move over the image without stopping, thus I was unable to precieve the rotation until it was brought to my attention to look for that. Now I see it whenever I look at it.

I always see the rotation except for the middle one or if I focus on a specific one that one stops spinning. I had my mother look at it and she didn't realize it was spinning until I pointed it out.

Dead people.

No, I see very slowly moving circles.

The farther into my peripheral vision they are the more they seem to rotate. I can make them all stop moving if I concentrate really hard but it hurts my head.

Not every circle is rotating. Only the big ones and "half-big ones". But it's because the way they are made in spiral-form with different colours. And they don't rotate when you fix on the middle. I guess, NT's see it the same way or not? But I like all this "brain-games". There is also the "spinning ballerina".
Is it okay, that I post it in this thread?

If I look at the middle circle all of the circles seem to stop moving, and if I look at any other circle the circles near that circle seem to stop moving.

The four circles that are complete, and the four at the corners appear to spin when not looked directly at.
The one in the center, and the four on the middle edges do no appear to spin.
The spinning goes in the direction of whatever side the blue is on.
And It seems that more than 50% of the circumference of the circle needs to be visible for the effect to happen.

It does not make me feel uncomfortable in any way to look at.
