As the original poster of the Ruler, I suppose it is up to me to get
this newsfroup back on track :-).  I might add that I have briefly
become famous in our lab, because the Ruler was the most-followed-up-
to-article on the Usenet for a two week period.  Anyway, the code that
follows prints a copy of an interesting stylized "N", that I found on
the cover of an Adobe font catalog.  The catalog itself is titled "Font
and Function", and I recommend it highly for all the page design hints
they include in each issue.

I am not claiming that my implementation of their design is
particularly clever or original, but it does raise some interesting
issues.  First, the design on the cover was the same size as theirs
on the cover, but theirs looked a lot better because it was at
significantly higher resolution than 300 dpi.  More importantly, when I
printed the same design 7 inches across on our Apple Laserwriter II
(Serial # CA850LM3%M6000, Manufacture date: December 1988 M), there is
a tiny black dot in the exact center of the concentric circles.  I
certainly did not intend for this dot to be there, and it does not show
up on the reduced version.  Is the dot a result of finite floating
point precision, or because of my method of clearing out the center
circle:  setting linewidth to 6, and drawing a 3.5 radius circle?
