When I first saw the site, I was hoping there would be a way to upload a picture, perhaps do some kind of feature-tagging (similar to the way you point out your pupils on photos on those try-on-glasses apps[1]) and have the site spit back a suggested face based on the features they had that most closely resembled yours.
Of course, this is complete spitballing, I have no idea if it's feasible.
