Hmm... would this work literally? Say, take one of those
laser level things that scans a laser beam in a plane
(spins a mirror I would think) and place it right up
against a very flat, very long, white wall.

Someone viewing this wall at right angles should see this
spot of laser light moving at very fast velocity and thus
the light would be "spread out" and shifted in color?
