Four Perfectly Round Circles

squinting a lot helps to see them better too. trippy!

This made my head hurt.

I see the dolphin.

Ohhh, yeah headache. It was like the big red 'don't press' button, I had to do it.

Its not a schooner... it's a sailboat

I'd love to have that on a T-shirt

What just happened? I think I had a mild seizure and now I can't uncross my eyes. Damn you karma!

Photoshopped!!!

Now my eyes have a headache.

Blurring your vision by altering your focus point helps to see the circles too.

In the spirit of irrational comments.... FAKE!

Hey gang,

I print tshirts. If anyone wants this on a shirt, I can get it to you for $15. Email me at team@recycled-tees.com

Thanks!

It looks more like a rabbit to me.

I thought PORNO wasn't allowed on this site!

Hey, that is pretty good! I do see 4 circles when I squin my eye! : ) Kool illustration!

Seemed like a spiral to me at first. Focusing on the circles and following them with the eyes all the way around helped...

i found it worked best by tilting the screen away from you.

Woah! That's a good one!

all I can see is a spiral.

It's a face AND a tree.

I only see squares. I paint them too. Anal or what?

Neil is right. By blurring your vision you can see that they are indeed perfect circles. Well, squares that are put in a pattern to form a circle.

There are inly squares here, any circles are simply imlpied...

I turned into a zombie after looking

This has been photoshopped. If you look closely you can see pixels.

Now that was like riding on a ride at the fair. Started getting dizzy there for a minute.

you can run your curser around each circle and see that they are all four independent of each other.

it's called an optical illusion, where have you people been? under a rock?

An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, tilt, color, movement), and cognitive illusions where the eye and brain make unconscious inferences.

Excellent. I love these kind of pictures.

A lot of work must go into them, to do them right.

whoa ! free acid for everyone.

Um, I got nothing but very mild eyestrain. I think you need two eyes to see this illusion.

This makes a perfect logo for a navigation company. Everyone who can makes sense of the logo will be intrigued, and all others will need their software to decipher it anyway.
