Ad for Child-Abuse Hotline Uses Lenticular Printing to Send Children a Message that Adults Can't See

The ANAR Foundation, a Spanish child-advocacy organization, faced a challenge when trying to create an ad that could offer help to children suffering from abuse, without alerting potential abusers (i.e. adults) to their message. The solution came in the form of lenticular printing, a technology that allows printed images to create an illusion of depth or, in this case, the ability to change or move as the image is viewed from different angles.
