Coke's long running happiness campaign has reached out into the real world. They have created a Coke machine with a difference. It does things to make people happy. This ambient idea created by Wieden + kennedy was placed in a Student cafeteria in the US. In my opinion it's pretty cool. But bloody hell is it unhealthy. Giving people pizza's to go with their cokes? Giving people 10 cokes instead of one. Maybe they should re-name it the Heart Attack Machine. But anyway it's a nice idea and it certainly seems to work. Just look at those happy faces.
