Here is yet another impossible shape. You’ll notice that the shading ads to the effect of this optical illusion.

Here’s a quick memory test: Take 30 seconds to look at this optical illusion, then look away from the screenand try to draw this optical illusion on paper. It’s pretty tough unless you have a photographic memory!

Looking for a cool optical illusion…this is sure one of the craziest you would have seen.

Totally straight lines, but it sure looks like this wacky checkerboard is bulging right off the screen.

If you don’t believe it, just hold a peice of paper up to test the straightness of all the lines. And, if you’re truly up for a challenge. Count how many squares there are.Otherwise, you know what to do!
