Find your long lost twin on Facebook

If you've always reckoned you have an evil twin somewhere else in the world or that you were separated at birth but no one's got round to telling you, Coke Zero's 'worldwide social networking experiment' could help.

Coke Zero has created a Facebook app called the 'Facial Profiler' which has the aim of finding people's online lookalikes.

The app encourages people to upload a photo of themselves to a database, Coke then analyses the characteristics and attempts to find the nearest match from other uploaded images.

The idea behind the campaign is: 'If Coke Zero has the taste of Coke...is it possible that someone out there has your face?'.
