This is pretty funny. By combining tweeting to a machine to get stuff, with the animated screen showing "the inside" idea seen in Lays vending machine making fresh chips, with the hilarious Jobsintown idea of people working inside small machines, we now have an interactive ad at a bus stop. To add to the funny, it's soccer star Gary Lineker that's inside the machine. People sincerely believe that it is Gary in there, because he's reacting to them, this bit of magic likely done in the same manner as the Adobe photoshop live street retouch prank. My favorite is when Gary holds up a note saying "Here's your bus" and the woman waiting looks quite shocked. Oh happiness machine, you seem so quaint and old fashioned now.
