Is anyone familiar with John Whitney's work 'Digital Harmony'?  Some of his
experiments show some very interesting features of harmonic inter-relations
that could quite easily explain the 'arms'.  Here is a simple experiment:
write a program that graphs a series of points and then advances them 
around a circular 'orbit'.  Initialize the points so that they are all
along a single radius line of the largest orbit 'circle'.  Plot the points,
then advance each point around it's respective circle an amount related to
the radius of the point's particular orbit circle (or inversely proportional
if you'd rather).  Since each point is traveling at a different speed, the
initial radius line will bend around to the point where it will 'wrap' on
itself over and over etc.  At certain points, the individual points will
'align' in different ways, creating a variety of spiral 'arms' and similar
features.  These 'arms' are related to the frequency 'beating' of the different
points.  In fact, eventually, the points will again align themselves to the
initial straight line radius pattern.  Such arm-like characteristics can
come and go at various times throught the lifetime of this experiment.
