Watch The Donut, Not The Hole

If you’re like me and are sick of all the tired old optical illusions people keep trying to blow your mind with,* you’ll appreciate an actually new one for a change:

Contrast Illusion.

I honestly can’t see the unison until you take the surrounding discs away. It’s a very convincing illusion, and for me it’s almost as frustrating as trying to reverse the spinning dancer’s direction.


*Like last night when a few of us were channel surfing and found a show, which may have been Numbers, wherein a man had drawn the infamous Rubin Face Vase and was saying dramatically, “But wait! When you darken the middle of the vase you can contrast the inside and the outside, and what do you see?” To which our pal Josh added in his even more dramatic Mighty Voice, “The answer may SHOCK YOU.”

This prompted a wave of shocking revelations from the rest of us: “The cavemen are the SAME SIZE!” “The two tiles are the SAME COLOR!” “The lines are all PARALLEL!” Amazing!

Yay, another person like me! I, too, could see the circles flashing in unison after unfocusing my eyes for a bit.

That dancer however, still drives me crazy. I can't make her turn counterclockwise. Sometimes she switches but I can never hold it or recreate it.

Hint?

Focus on the foot hitting the ground on whether or not its the left or right foot. When it switches for me, it's really weird. It's like she just crosses the screen and back.

Hope that helps ;)
