      Poopheads! I’ve been drinking beer all day and I did NOT need to stare at that for a while trying to figure it out! 😉

      It’s not moving at all. It’s just a sequence of images shown one after another. Persistence of vision may cause us to believe that the image is “moving” clockwise or counter-clockwise, but nothing of the sort is actually happening.

      The “Colour perception” is drop dead amazing! Grey and yellow are the same colour? Amazingly they are !

      Well, just focus on one dot at a time. You’ll notice each dot is part of a ring of dots “moving” at a constant speed. The outermost and innermost rings move clockwise. The middle moves counter-clockwise. Between these are graduated levels of speed either slightly faster/slower than the one before/after.

      I prefer the spinning dancer (clockwise or anti)?

      @2 If you didn’t drink beer all day we could call you something else.

      I think I could have gone all week without seeing “Mindbender 2” from the link.

      Now the walls keep breathing. Aaarrrgghhh!

      #5, Tihz_ho, nice link. Did you see the link cagematch credited? Light green is dark green.

      #6, the.arctic, That’s darned close. There are also some subtle position jumps where dots move in and out of rotational “rings” that makes the illusion even more confusing. Good job.

      Yes, I had a look – great stuff! I always loved the colour illusions from years in the sign business long ago. Some clients would drive you mad with wanting the colours “just right” so I would whip out one of these colour illusion tricks just to bend their mind for a while.

      Cheers

      I hate each of you guys.

      A whole bunch.

      I’d like to comment but seem to be having an acid flashback flushback.
