There’s a new Facebook called Facial Profiler, it enables you to find people who look exactly like you. Here is what i gathered from an article from Gather.com about Facial Profiler:
The Facial Profiler, a new facebook app, is actually an ad campaign launched by Coke Zero, its point being that the calorie-free version is so much like the real thing, they can prove it by showing that every single person on the planet has a doppelganger. Here’s how it works: you upload a photo of yourself and you’re matched with a similar-looking Facial Profiler user. The idea is that you can find your mirror image, just the way Coke has in Coke Zero.
The concept is quite old but Coca Cola is able to give it a new twist.Here is the sreen shot of the Coke Zero Facial Profiler page:
