Caromatherapy

The Whiff Guys, sensory specialists, report on caromatheraphy experimentation by Mercedes-Benz. Read it as car-aromatherapy. Admittedly only in the luxury limo division, but more about personalizing contexts in which we live. See their site for more advances in sensory marketing. Also see their book: Whiff!: The Revolution of Scent Communications in the Information Age.
