As this story from Advertising Lab tells us, the Royal College of Art-Platform 11 has developed an ice cream kiosk that will dispense a portion of ice cream commensurate with how happy or sad the user is. Having a bad day? Voice sensors will detect the stress in your voice and dole out a healthy portion of the cold, creamy manna (I'm an ice cream addict, if you couldn't guess :). Not so unhappy? Then you can afford to cut back on the calories and save more for those who may need it. As Demitrios Kargotis, the kiosk's inventor, simply states, "the more unhappy you are, the more ice cream you need."
