I'm having trouble seeing the squares...

Focus on a single point, any will work. The illusion will present itself in a few seconds.

Reminds me of those crazy Magic Eye things from the 90's.

If I don't have to strain to see the circles, does that mean there's something wrong with me?

Now I can't UNsee them!

Look in between two of the squares to see the circles, and look in between two of the circles to see the squares. circle-opt...2cb501.jpg

I was trying to find 16 before I opened the whole picture lol oops

I searched for them for a whilre, then a just rested for a second and then highered the brightness! Now I see them :D

I couldn't see them right away, but I tried changing focus and they appeared for me. I wonder if this would be a good device for training the muscles of the eye because it forces you to change focus to see it differently.

It took me a minute but I finally found them right where I’d been looking.

Took about a minute. I slowly crossed my eyes until 3 rows of 5 circles appeared. It was like they were sitting on top of the squares 3d like. Weird.

A circle, by definition, is round and is depicted by a curved line. however, in this image all the lines are straight suggesting there are no circular shapes.

BS ... only squares.

YES!...at last!

took me a min but I see them all.

circles with square corners, yea I see 'em ..

This is a stereo picture 20 circles

I see them, but they are not really circles

Yes.. I saw them... just need to focus - it just pops up all of a sudden, so to say.

With a slight refocus of the eyes the Circles jumped right of the page. Reminds me of the abstract prints with wiggling lines and colors with an image hiding inside popular back in the 90's !!

so boring... I can easily switch between circle view and square view....

I found them! Its easy if you put the background out of focus

I was just about to call you all crazy! Then by moving it away and close a couple of times they just popped out at me!

Put your eyes in a trance. Like when you first wake up and you stare. You will see them

The 16 were easy. They popped right out. but when i shift my vision into a 3D mode, I am able to see 20. Several people have told me that I am crazy that there are not 20 circles visible in any way but in the 3D mode there are clearly 4 rows of 5 circles. Can anyone else see these? We may be a special tribe.

Took about 20 seconds, then I let my eyes relax and then the circles (not my eyes) popped right out.

I saw them only after I relax myself, and trying not to focus so much

What is once seen, cannot be unseen ....

Took me a little while but finally seen them. Went back and looked again and had to refocus because I didn't see them again even though I knew where they were.

Took a minute but the circles suddenly popped out!

I see them when I open my eyes really wide.

Not at the beggining, but after a while I could see them.

I finally found them all by staring at it for a long time, but I discovered that I can make ten circles immediately by putting the tips of my thumbs and fingers on the touch screen. I could get even more by adding toes, but can't quite make that at my age.

Now I see them, but then I lost them

i CAN SEE THE BOXES AS WELL AS THE CIRCLES

Awesome! takes awile to train my eyes! I even saw stars....1000 of them!!!

I saw them immediately.

ooh thats cool! if you are having trouble seeing them. look at the boxes then shift your eyes to the right but focus left.if that makes any sense. once you see them u will understand what i mean.

i love these! more please!

There are no circles, there are circular shaped objects that can appear, but do not fit the definition of "circle" a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).

Megvannak.

I can see both circle and square

Found them right away
