The drinkin' tinkerers over at Instructables created the Serv O'Beer to interpret a "pouring" motion with an iPhone into a real, albeit foamy, beer. What an age we live in!
Creator "Polymythic" used a Construx building set as his mechanical base and an ioBridge to control the system. It pours the beer a bit violently, just like this previous hack, but if you're drunk enough to insist that tipping your iPhone should result in a real beer, it should do you just fine. [Instructables]
