Terre des Hommes wants to help the child prostitutes in Cebu, Philippines. With the insight that most of them don’t know where to find help to get out of their miserable situation, New Message created a bridge between on and offline, by creating a website (built by 9Yards) that allows the crowd to place physical arrows in the streets of Cebu pointing to the local offices of Terres des Hommes. Every donation is worth an arrow – both virtual as well as physical. We’re not quite sure how effective this campaign will be (if you zoom in on the map only a tiny part of the entire road is paved with arrows), but it’s yet another example of transforming online engagement into offline impact – with the help of the incredibly handy Google Maps API.
