ANAR, a Spanish organization that helps at-risk children, found an interesting way to target only the people who needed their services, without their parents finding out they wanted to get help -- a lenticular photo.

If you think you're unfamiliar with lenticular photographs, you're probably not -- they're those pictures that used to come in boxes of Cracker Jacks that changed from a regular guy to a winking guy when you moved it up and down. Sometimes they are called "wiggle pictures."

ANAR calculated the average height of 10-year-olds and made a lenticular advertisement so they could read the phone number to call for help without their adult abuser realizing they were thinking of calling somebody.

A smart advertising move that will hopefully help children who otherwise would be too afraid to ask for it.
