Hey people! Be careful not to stare too long at the animation below, it can cause dizziness or possibly epileptic seizures. Don’t say I didn’t warn you :) It’s little scary as well. Look how that strange girl’s face appear to constantly and fluidly move to upper right corner of your screen, while in fact, the animation only loops forever. Because of black and white negative blinking, the face appears to move only in one direction (you don’t see it moving back, when the animation loops to its start). I have another great example of this! Check Christopher Walken optical illusion and Scary Spider illusion. They both give you the same effect. More can be found inside our Scary Optical Illusions category. Oh, I almost forgot our most recent one – it is called “Flying through city“.

    It’s a guy, not a girl. Unless the girl has hair on her chin…

  • Anonymous

    Maybe, I’m nto sure. IT looks like a girl from te face and the hair, but the chin does look boyish. BUt seriously, does it really matter?

  • Shauzia

    Pointless. The backround is the only thing moving. The pic is just flashing. To the B to O and the R and I and N and G, What does that spell? BORING!

    Why is there a page of a google search results in the background?

  • John

    To the person who said that this boring, I am waiting for you to post a better illusion, until then don’t be so quick to judge.

  • Tim

    Very cool! Keep up the good work!

  • Tim

    Which is the background and which is the image depends on what colour the DJ is – the neagtive space (white) and image (black) reverse when the colours switch, which has a fair bit to do with the illusion.

  • Jesse

    ummm… cool, but…
    it has a beard, it’s a guy.
    and why’s it scary?

    Well put, John

    its a dude with dreds there happy? lol

    The illusion looks like it’s moving because the text is moving. The text is probably google text results because you’re probably very familiar with seeing them scrolling, and thus you don’t think twice about them.

  • devildog

    It looks like you just copied some random ad for a website. Probably an ad by google. Dissapointing.

  • devildog

    It looks like it’s just an ad for some random website. It’s probably an ad by Google, which would be why there is something in the background. Disappointing

    “Epileptic seizures can sometimes be triggered by certain frequencies of flashing or flickering lights, or by certain geometric shapes or patterns.” epilepsynse.org.uk

    “Migraine Triggers: … bright or flashing lights…” bupa.co.uk

    Enough with the flashing lights already!

  • Kaeo

    If you click and drag the image it will freeze so you can get a better look at it. I definately think it’s a guy and the image is the white face with black hair. It is interesting how it keeps moving to the right though.

  • Ribbed

    Always interesting to see what people can do with this effect. While it’s not one of the better examples, it does demonstrate the sense of constant unidirectional movement quite well. Good use of the background text as well, 2 directions in 1 picture.

    Another thing I found interesting… when a “good” illusion is posted, a dozen kiddies are all proclaiming “first post!!”, like seeing a “cool” blog entry before anyone else somehow makes them the better person. But when a not so good entry comes along, y’all are too busy bitching about it to even care if your first or not. I cast my vote for more not so good entries :)

  • Elliexx ANIMALS ROCK!!

    yeh, go u John; i agree. kl illusion, but as Vurdlak said, it does make u feel dizzy after a while!! lol

  • AK

    Wateva u guys say, this illusion rocks. I love the effect, and i thought the guy/girl was moving at first glance. I dont like the text though, maybe there is a better way to do it?

  • Anonymous

    Whats wrong with girls and facial hair anyway??

    (Joke btw. i am a guy.)

  • Dogmanov

    Epileptic seizures are triggered between 4-20 Hz, which this image may fall foul of… Other than that, it just looks like another annoying banner ad… Not good when you’re trying to work using other OS X widgets, makes you want to turn the offending one off!

  • Anonymous

    NEITHER the background or person is moving, THAT’S the illusion. If you don’t believe me, cover the picture except a small hole and watch it. Nothing is moving, just flashing.

  • Tim’s Movie Site

    Okay – enough already. I have your gadget on my google homepage and it’s starting to give me headaches to have this flashing in my face every time I go to look at the new news!

  • Anonymous

    Had to take it off my desktop -it was driving me crazy with that flashing.

  • Anonymous

    is that google in the backround?

  • Anonymous

    ughhhhh my head hurts. this image does give dizzyness…..

  • alex_can_fly

    Liked the City one better, but still a great post! Keep up the good work!

  • Nutty Cone

    This isn’t scary at all! And its not a girls face, its a guy.

    Thanks, anonymous no.41 at 3:39pm- i honestly never would have got that!

    And I have decided this guy is NOT who I thought he was- the beard isnt long enough. (but yes, it’s a GUY)

  • Anonymous

  • Anonymous

  • cuppycake

    No, it is a girl. And that’s not hair on her chin, its a shadow..NOT hair..shadow..

    And this is a little boring..just not feeling it.

    I think it’s funny that someone thought that only the background was moving and not the face. The face and the background are both doing the exact same thing! They are both flashing back and forth between two different positions, and they both appear to be moving constantly in one direction, but never actually do. Very effective illusion imo.

  • Gabriela

    THAT’S NOT AN ILLUSION!!!

    It does move… check the .gif the different images move a little but they DO move…

    There are 2 white images and 2 black ones, the first in white is in the center and the next one also white, moves up a little… same with the ones in black…

    And what’s with the google search in the background

  • http://idk.com charlotte

    what is the point of doing theese illusions if you cant even watch them i think that you need to fix your website so u can atually persuie what you are trying to advertise!!! thanks so much!

  • Franx

    It’s creepy how the “scary girl” has a goatee… really kwl, tho.
    Cheers!

  • Pyro

    BE CAREFUL, SHE IS GOING TO PRESS THE EXIT BUTTON!!!!

  • randommmmm!!

    its a guy not a girl

  • nobody

    what do i google to find that????

  • !!me!!

    ohh scary.. NOT!

  • Bob

    by the way nothing in the picture is moving. It’s jutt changing colors. You can test this by puting ur finger righer under his eye… u will see that it stays in the same spot.

  • Wow

    it burns my eyes

  • tacos

    stupid that causes seizers than why are they showing it to us GOSH PEOPLE

  • Shaleha

    UM?

  • Starlet

    that is no girl, unless you’re gonna say a girl has a small beard

  • E.Gautham

    according to me, the picture with white background looked much like a guy and the same image with the black background looked like a lady.

  • Anna

    i see how the ‘girl’ loops

  • Al

  • keira

  • Bob
