I was browsing the internet today. I found this scientific effort from Dr. Steve Aprahamian. He has created a timeline chart of the famous Christopher Nolan's "Memento." The film starts with a Polaroid photograph of a dead man. As the sequence plays backward, the photo reverts to its undeveloped state, entering the camera before the man is shot in the head. The film then continues, alternating between black-and-white and color sequences.
