Well recently I got an email from the creators of Facesaerch about the amazing new image search engine they have created.
Facesaerch basically helps you find face images of people and celebrities. It is powered by the Google Face Search technology which was unveiled by Google in July last year.

The image results are highly accurate and animate in a fancy cover-flow style which you might have experienced while using a Mac or iTunes. Other than celebrities, Facesaerch works good for finding pictures of common people too.
Facesaerch also has a Facebook app called FriendlyFlow which lets you browse your Facebook friends visually and receive live updates of what they are currently doing.
