Sweet & Nerdy
Stokholm has interactive billboards you can control with your smart phone to earn McDonald's goodies.
You pick your goodie, then play the game in real time on the billboard. Your phone is the paddle. If you last more than 30 seconds you earn a coupon for the goodie you picked out. You have to be within range of the billboard to play the game. Come on America! Get with it!
