Spine Drift Illusion

Was just wondering what’s been going on with our Japanese professor #Akiyoshi Kitaoka lately, when I received this amazing submission from one of our fans – featuring recent work done by our favourite professor. Yes, similar illusions were featured in the past, yet the inset in this one just won’t stop moving! I’m not sure you’ll be getting the same results I did, specially since your “tiredness” factor heavily influences the motion… BTW, you might want to slightly scroll the picture up and down, or tilt your head around to experience even stronger effect!

  1. I like the way that it only moves from some angles; you can’t MAKE it do it. It also seems to do it when it’s slowly scrolled down. I find that if I look at it straight on, it stops; you just have to catch it in the act. Excellent illusion.

  2. Its amazing to create the illusion of movement to the viewer only by turning the “black/white” 4 pointed-stars to a different orientation.

    If the inside diamonds are rotated 90 degrees to match the outside diamonds, the illusion of motion is gone.

  3. Freaky. And surprisingly entertaining! Also, I really like the choice of colors and shading.

    And what’s really cool is to scroll such that a line of “stars” is along my browser’s edge, which shows:

    Their lines are purely horizontal and vertical, not tilted!
