Diana Hughes from the University of Southern California created Pluff to function is a combination Furby/Tamagotchi pet that's both a controller and a virtual pet. Petting him makes him happy, slamming his head against a desk makes him sad. The better you treat him, says Hughes, the easier it is for the user to teach him tricks.
All I can say is "Want!" And I can say it as many times as I like because I'm a chick and feel no shame in loving fuzzy things.
