With only three touches to the screen, you can add your face to a Naavi (from the movie Avatar), a medieval knight, a motorist, or even Rambo himself.

It is ideal to create avatars or user icons, but if you want to improve the appearance of a normal photograph, it may be better find another, more serious application.
