Edwards, a Harvard professor and head of science/art innovation lab Le Laboratoire, just unveiled the first commercial version of his oPhone, the DUO,  a cylindrical gadget that transmits scents (called oNotes) via an app called oSnap. Think of it as a mobile messaging platform for sending aromatic emoticons. The oPhone might look like a strange medical device, but Edwards is betting it could usher in the beginning of the aromatic communication age.

We wrote about the oPhone a few months back while it was still being designed and developed, but Edwards and his former student Rachel Fields has recently launched an Indiegogo campaign for pre-sales (you can buy your own oPhone for $149).
