People like Dunkin' Donuts coffee. People like Facebook. Thus marrying the two in the mobile space was the idea that fueled Hill Holliday's creation of the Coffee Customizer. Users were directed to build their Dunkin' Donuts beverage on their mobile phones, either within the Facebook application or via Facebook's mobile web site. The Customizer harnessed the available technology quite creatively, too: add creamer or sweetener was only a tilt or swipe of the phone away.
