Hey John, check out this animation that shows how galactic spiral arms
can be standing waves.  The animation starts with a bunch of things
orbiting a common center, the orbits pulled into ellipses and the
ellipse axes rotated according to distance.  Presto - a two armed
spiral galaxy!

Someone drew it, so it must be real.
