One of the more fun projects I've worked on, we pitched the idea of a customer-centric app for the popular craft-beer tavern, World of Beer. In this app, the user has the ability to view a live list of beers in their local tavern (with ability to filter), see their profile and their progress via a point/achievment system, view upcoming events, and get notification on deals. Also, it was a plus having to do some "on location" research ;-)
