After the AMBER Alert became widespread, pictures of missing children no longer appeared on milk cartons. Now a London-based charity, Missing People, is taking the effort a step forward by using digital billboards with 3D portraits of missing children. The pictures look “live” with blinking eyes and tilting heads. The billboards have a QR code to help spread the image and information on social media. The signs also use the words “help find” instead of “missing” because behavioral scientists say this will give the public a call to action.
