A clever outdoor ad from Sweden uses a bit of technology to transcend the limits of the medium.
Apotek, a pharmacy brand, outfitted subway platform ads in Stockholm with ultra-sonic sensors that discerned when a train was coming. The ad featured a model with a lush mane, and when the train came, her hair flapped in the wind and she struggled to keep it in place.
The tagline: Make your hair come alive.
The ad surfaced around the same time that another billboard, from IKEA, was using alternating red, blue and green lighting to express three different messages and underscore a point about maximizing space.
