#D "Aurora" rule by Rudy Rucker
#D 
#D The rule for Aurora is a one-dimensional version of the Rug rule:
#D every cell's new state is taken to be one greater than the neighborhood
#D average of Left, Me, and Right. When a color value reaches 16, it is
#D rounded back down to 0.
#D 
#D The effect produced is like globby paint running down the screen,
#D though really you are seeing "one-dimensional gliders" moving back
#D and forth and interacting.

#D Rudy Rucker:
#D 
#D "I called the rule Aurora because when I visited Norman Packard's
#D office at the Institute for Advanced Study in 1985, he showed me a
#D smoother (eight visible neighbor bits and 255 colors) version of this
#D rule and remarked that it looked like the northern lights."
