The Flower Power Illusion


Happy X-Mas and Marry New Year… or the other way round. I understand that during the hollydays you’re not much into illusions, or at least my visitor stats claim so. Anyway, I think it would be unfair to the rest if I slowed down with my posting rate. So for today I bring you a classic pattern that causes a well known animation effect. This flower was center piece on a poster made for a Brazilian website called “Flower Power”. I’m not sure what they’re into, but for sure they’ve created one cool poster. I assure you this is a static image. When you move your eyes around it, you should see the flowers move, as if the poster was animated .gif file.

    Always loved the illusions like this. Simple but very cool.

    I’M from Brazil. I can’t see it

  • egdirbr

    I like these subtle ones.

    Nice use of a classic illusion. =)

    It’s weird though. If you move your face forward and backward while staring at one flower, the flowers around the periphery look like they’re moving. The one you’re staring directly at never seems to move.

      I must be weird, but they all move for me.

  • Joanna

    So simple yet effective.

    Merry Christmas to those who celebrate it. Mine in Melbourne was perfect – weather, food, not too much drinking, family, music and laughs.

  • awesome

    Another classic but cool illusion. First comment, yeah!

  • Care Bear

    Merry Christmas and Happy New Year to you, too. I like the flowers but I’ll probably need a few more drinks of rum punch before I’ll be able to see them move. Thank you for a wonderful year of illusions and all the best in 2010.

    Your article dates Dec 26th, I must of lost a day somewhere I still think it’s Dec. 25th. Anyway, I love the flowers but I see no illusion. I keep rolling my eyes over it, but all I get is a headache.

  • Riaan Rossouw

    I love these illusons because of what they teach us about our vision system.

    Google “self animating line textures” (SALT).
    There’s couple of papers explaining how this and other “animated” illusion works, from there you can make your own in a couple of minutes in Gimp.

  • Steph

  • cole grose

    love this one!!you are so right when you said that THIS IS ONE COOL POSTER!

  • geek

    pretty awesome :) worked while reading the “instructions”

    1st ?

  • wowaname

    I can’t see it moving as well as the “wave” illusion.

  • Detective Kitty

    it’s interesting the effect it has on each person…how it moves for some and not for others…frankly I think it’s the black and white around the petals. In it’s curved way that helps your brain think that the flowers are rotating…but the one your staring at you can tell isn’t moving but in you periphil the black and white tricks you….truly a simple, old classic but amazing because it reminds you the old is better then the new….

  • lolipop101

    oooooh turning flowers how weird

  • Whats it to ya?

    LOL if you look at the flower pot, it looks like the petals are rotating!!!!!
