An in-house project from The Barbarian Group gives a modern spin to smiling at a stranger. Part of Project Popcorn, where a new hire is paired with a couple of Barbarians to create something innovative, the project lets you upload a picture of you smiling using your webcam. A "smile-sensor" detects to make sure it is a picture of you smiling (and not something Anthony Weiner-esque) and then gives you a picture of a stranger smiling back at you in return.
