Using a digital billboard in central Stockholm, we created an interactive challenge where you could pick and play for your favorite McDonald’s goodie. Steer the paddle by using the touch-screen on your phone, as you follow the game on the big screen. Combining JavaScript, HTML5 and the phones Geo-location we made it possible to interact with the screen in real time; without having to download any application. If you lasted 30 seconds you won your goodie of choice and a digital coupon was sent to your phone with directions to collect your prize at the nearest McDonald’s. Game on Stockholm!
