Like Smell-O-Vision for the 21st Century, this strange-looking device works in tandem with a free smartphone app and allows you to receive scent messages. For example, say you're out enjoying one of the most deliciously fragrant burgers of your life and want to boast about it to your buddy at home. You pull up the oPhone app, adjust the aroma dials to match the ingredients you're smelling, and send. Your friend, assuming he has the oPhone, will be prompted to take a whiff of the diffuser, which will be emitting the scent you dialed up by mixing together a unique combination of aroma cartridges inside. And good luck trying to stump it—it's capable of producing over 300,000 unique smells. Welcome to the future, everybody.
