Waaaaay back in time, in ad-puppy-school, somewhere back when dinosaurs roamed the earth I recall a classmate showed up to class with a drawing much like the first image shown here -though it was signed "Nike, Just Do It".

That as an idea, not so good. This as an idea much much better indeed. To garner attention for the Maximum Ride series about a group of kids who can fly, Colenso BBDO, Auckland, New Zealand created giant city-seen-from-above decals that allowed kids to get the visual impression of what it feels like to stand on the edge of a building and jump.
