Audi’s luxury vehicles include a neat night-vision system that will automatically warn drivers about hazards on the road. And to drive home just how life-saving it can be, the company’s ad agency created a brilliant billboard in an airport with a secret hazard that was only revealed to passengers when they got closer and closer.
Using a physical phenomenon called accommodation, the ad cleverly manipulated how the human eye focuses so that the slightly blurred text revealed an additional message — created using just outlines — as the viewer got closer to it. In this case it was placed in a spot where airport passengers on a moving sidewalk saw it guaranteeing the neat effect would be noticed. Remember, it’s all fun and games unt — A DEER! [Vimeo via Taxi]
