One mode combines movement with other visible properties. The effect of a rapidly swaying brilliant object may depend on its shape and light as much as on its motion.
Another mode depends on a collection of movements alone. Something moving right and left, upward and downward, can produce a distinct overall pattern when the movements interweave.
A list of movements is not enough. One must ask whether their directions, order and interaction produce a unified appearance. In a composite point it is this configuration that is intended, not each individual movement taken separately.
