Marcel Duchamp - "Sad Young Man in a Train"
In this piece Duchamp uses several techinques to imply motion. Of course, there is use of the multiple images. The figure of the "Sad Young Man" is repeated many times across the piece, each one a snapshot of a slightly different time. We perceive this as one motion much like a video or flip book. He also makes use of blurred edges to further communicate the movement.
