Check out MyHeritage.com. This website has a neato demo of face recognition. Upload a photo of yourself or family members and it will tell you in a few seconds which celebrity looks just like you.
This was fun! John looks 71% like Annette Bening and 61% like Tom Cruise. I look like 66% Kelly Clarkson and 60% like Julie Roberts. I guess because we have oval faces.
