In an effort to promote Coke Zero's extreme likeness to Coca-Cola classic, the brand has teamed with Crispin Porter + Bogusky to launch the Facial Profiler. The Facebook app matches your face up with other Profilers with similar mugs. It utilizes the same facial recognition tech used by law enforcement to locate faces in crowds. Visitors to the site can vote on accuracy of the various match-ups, which will ultimately serve help to refine the system.
