I always enjoy optical illusions. This one was sent to me recently in an e-mail, and I must admit that I stared at it for a long time. Take a look… Count the people and then wait. Are there 12 people or 13 people? No portion of the image is added or subtracted, only moved… How’d they do that?

Are you stumped? See the illusion explained at:
