I found this optical illusion through my Google Alerts email, and noticed it’s pretty interesting. At first you may miss the illusion, but if you watch carefully the center of the brown “dot”, you will notice that it appears to be expanding. The effect by its nature, is quite opposite from other illusion located in disappearing effect section (which I updated just now), but it works in the same way. Just think of it like this – the center blurred spot isn’t vanishing, rather expanding, but the outer yellow surrounding is slowly shrinking (disappearing). This is the reason why I placed it in the same category. You may want to check stronger examples like vanishing haze, but you should also visit expanding cushion and expanding block that aren’t much similar, yet they also seem to expand.

    hmm, if I stare at the brown dot as it suggests, mine also tends to shrink almost to disappearance.
    Though, if I look at the edge of the brown dot (or anywhere in the yellow) it seems to expand.
    Bizarre! I like it!

    For me it seems to jump around like crazy and when I look at something else, I can see it as a negative ghost.

    when i look directly at the brown dot, nothing happens. but when i look away from the picture, the brown dot seems to expand in the corner of my eye. when i look back at the brown area it shrinks again. Kl!!

    this works becuase ur eyes adjust to the darkness and then the outer fading browns be come darker, meaning the shape appears larger.

    Shrinking, expaning, I think they’re the same thing. For me, at first it was just moving around up and down and left and right, but then, I got the whole screen to turn LIGHT BROWN, which you could say is… I dunno, do you call it more yellow, or do you call it more brown???

  51. Waz UP? says:

    if you go down then it gets bigger and if you go up it shrinks…

  52. jaylen says:

    very cool. if you look long enough, it also seems to move around. (:
