From spinning circles to disappearing dots, these insane optical illusions aren't what they appear to be. Are you ready to have your mind blown?

Your eyes will keep jumping to the spinning sunbursts of seeds—even though they're all staying still.
Hidden message
Lose your focus a bit (seriously—try to go a little cross-eyed) and you'll spot a secret message hiding in the black dots. Take a closer look, though, and the words will disappear from sight. We bet you didn't know that these famous paintings also had hidden messages.
