DDB Stockholm launched last week a new billboard very interecting on behalf of McDonald's. Assuming that the majority of mobile phones are equipped with cameras, they have launched an interactive billboard.
The principle of this billboard was to march in every direction objects such as balloons, glasses, etc. and also McDonald's product such as a coffee, or a Sundae or a pie, if you could catch one of the products from McDonald's with your camera you could get it for free in the nearest McDonald's.
