I found this pretty interesting. You place your picture on this site and the program (Gabitus) matches your face with celebrities with similar features.
"OK. Right now you have a possibility to compare yourself impartially with the top celebrities in the World. We do not know you and have no reasons to make things better than they are. Our engine Gabitus® will find most matching similarities between your portrait and 200 photos of Top Stars. Gabitus® will recognize you. It will show 3 best matches, and, finally, only you decide if you are looking like those famous persons"
I nearly always get these same three (one of them I'm embarassed about )
Mark Dacascos (Close, Filipino like me)
David Beckham (Not Close at all)
Mr. Bean (...)
