Circular Optical Illusions Collection

Before I try and explain today’s optical illusions, I’d like to take a minute of your time and ask you for a little favor. As you know, we have published the Vista gadget recently, and it’s been doing great ever since! Over 50,000 visitors have downloaded this app and enjoy it for free. I have never asked you to donate, nor pay for any of this stuff, and I will never do. But to keep this hobby alive I need a little help: if you like this gadget as we do, please login to Vista website (you can use MSN login and pass or you can register), and vote our gadget with 5 stars. I hope it deserves it!

For today’s illusions, all I can say – they’re pretty circular! It took a lot of convincing before I believed that every single picture posted represents regular (concentric) circles or spheres. In some examples you may even think that the “curves” are actually spirals, but I can assure you that you would be making a big mistake! Many similar examples were already posted – you can check them in our archives. Which example was most insane?

  1. I like ’em.

    The one with the green background sends my eyes all loopy! Definitely gets my vote for “most insane”.

  2. of course I will vote for you!!!!! I love your site, thx to igoogle I discover that gadget, and then your site, I love it, the problem is I dont have windows vista.

    I hope youre having a nice day, take care!!

  3. Talk about hypnotizing!! For the second one (black and white, not green) it’s the white at the top/bottom/left/right edges of the circle that makes you think they aren’t completly circular.

  4. I love the green one its crazy! Sent it to my dad =D

    Sends my eyes all loopy!:P lol… try it as your background maybe?

    i don’t like the bottom two though – probably because i don’t know what they’re supposed to do – maybe just look a little square/straight edges because of the pattern? but meh :P… I think they were easily made in, for example, paint shop or photoshop using the transparent ‘colour’ (the squares) and then blurring from a screenshot of it(from deleting a circle from a white bg fro example)

  5. The thing about the third picture from the end is not whether it’s concentric circles or elipses: It’s that there are no circles there, just weird yellow shapes that make it look like there are circles, and that’s pretty cool.

  6. For the bottem two, when you stare at the center the edges look like they’re vibrating. At least thats what I’m getting.

  7. Nice pics ;) Acturus right. These are good pictures to do hypnosis on yourself. Personally, I use this kind of animated gif (or jpg) to do a job and meditation led attempt to drive what is wrong with me.
