Last week, I built a fun little quizzing application where three random meme faces are shown to the user, the user picks one and imitates it, and then the computer guesses which face the user is imitating.
It compares detected/aligned/cropped faces and features computed on those faces. Here are some side-by-side cropped impressions.

|Not bad, computer. Not bad.|
