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. Keith Doyle # {ucbvax,ihnp4,decvax}!trwrb!cadovax!keithd
