The multiplane camera is a motion-picture camera that was used in the traditional animation process that moves a number of pieces of artwork past the camera at various speeds and at various distances from one another. This creates a sense of parallax or depth. One variation is to have the background and foreground move in opposite directions. This creates an effect of rotation. An early example is the scene in Walt Disney's Snow White and the Seven Dwarfs where the Evil Queen drinks her potion, and the surroundings appear to spin around her.
