At first glance, it looks like these kids are about to jump off a high-rise building. Look a little bit closer and you’ll notice that it’s all an illusion! This extremely clever ad campaign promotes “Maximum Ride,” a series of books by award-winning American writer James Patterson. "Maximum Ride is a series about a group of children who can fly,” says New Zealand-based ad agency Colenso BBDO. “To launch the latest book, we created a large ground decal that showed Aucklanders what it was like to stand on the edge of a building and jump."
