This is pretty interesting. The Spanish child advocacy organization, ANAR, launched an outdoor campaign that uses lenticular technology to deliver different messages to children and adults. Lenticular technology is that thing that makes what you see change based on the viewing angle.
Grey Spain created messaging that only children — or anyone under 4′ 3″ — can see and a separate message for those who are taller. The message seen by taller folks is “Sometimes child abuse is only visible to the child suffering it.” The message seen by shorter children is, “If somebody hurts you, phone us and we’ll help you.”
The differing messages reinforces the underlying fact that many times child abuse is, in fact, only realized by the child and not the adult. Nice work.
