An "pretty" function is illustrated on page 34 of the January 1994 issue of
The College Mathematics Journal. You can duplicate it on your TI-82 or TI-85
in polar graphing mode with the function
r=cos (5 theta)+{-5,-4,-3,-2,-1,1,2,3,4,5}cos theta
(theta is, of course, the graphing variable)
A reasonable viewing window is
theta= 0, pi, .05
x=-5,6
y=-3.5,3.5

I left zero out of the list of integers to reduce clutter at the origin.

This is a nice demonstration of the use of a list to graph a family of
functions.
