The UID Cookie Box really makes you work for your snack, but the tweeting cookie dispenser will reward you for your efforts.
Designed by Daniel Jansson, Alexis Morin and Sharon Williams, the UID Cookie Box dispenses a cookie to the person in line once they send a single tweet. Unlike most vending machines, this one only offers the crispy treats. The display will also tell you what you'll have to tweet, as well. Unfortunately, if you're looking o satisfy your massive cookie craving, you'll have to head elsewhere.
The cookie box keeps track of each participant, so it limits one cookie to one user. If you're really that desperate, who says you can't create a couple more accounts on the spot?
