The Harvard professor that brought us a real life smell-o-phone has announced that he's expanding his olfactory-focused products to include eBooks, songs and clothing. Now clothes that give off a scent isn't that weird, but eBooks and songs? How does that work? Professor David Edwards is calling these unusual digital tomes and music "oBooks" and "oSongs," and they pair up with his company's, Vapor Communications', "oPhone" contraption. That device (see above) contains all the scent chips meant to be mixed until it matches the specific scent indicated by the files. When it was launched last year, it was only good for giving off scents attached to messages indicated by the sender through its accompanying app.
