We’ve posted stories on pop-up vending machines that offered free coffee in airports, free beer, free sodas and even free chocolate. Now the Australian branch of the Cadbury candy company has rolled-out the “Joy Generator”, a vending installation that dispenses a variety of 12 different chocolate bars.

Users simply sign in with their Facebook account and they receive a free candy bar with a flavor based on their profile. For example, if the Joy Generator classifies a user as sociable they will get a Rocky Road bar and if they are deemed adventurous they get a Turkish Delight.
