I tried it out with a picture of Brad Pitt. The results are NOT close, unless you think "Yes that's a white male" is close. The hair color was wrong, but that could have been due to using a picture of Pitt where his hair is dyed blond but his black roots or showing, or just due to shadow.<p>I guess they have many hundreds or thousands of images pre-generated, and when you upload a photo, they find the closest ones.
