An new ad from Spain is taking an innovative approach to combating child abuse - by sending out a secret message on posters that can only be seen by kids. The ad, from the Spanish children's advocacy group, Aid to Children and Adolescents at Risk (ANAR), uses lenticular printing, which allows different images to be shown on the same display, depending on the angle from which it is viewed.
So an adult who is looking at the ad will see one thing, while the child next to him will see something else. In this case, the adult will see a picture of a young boy with the message, "Sometimes, child abuse is only visible to the child suffering it." The child will see the same boy but with bruises on his face and the message "If somebody hurts you, phone us and we'll help you."
This YouTube video explains the ad and the technology behind it. Take a look:
And even if it just helps one kid get out of a bad situation, it will be well worth the investment.
