Conan O'Brien Lets People Check In to His Blimp on Foursquare
New York agency Breakfast created a "trackable experience" for Conan O'Brien's blimp. For the blimp's tour of the Eastern seaboard during the month of October, Breakfast made it possible for people to check in on Foursquare when they saw the blimp fly overhead. Doing so would garner the Foursquare user the Conan Blimpspotter Badge. You can track the blimp's location here.
