The source code that I put below the dotted line shows
an unusual way of employing the "faces" object.
Teachers of math and/or computer science might want to
challenge their students to figure out how and why the
program produces the visual output that it does. The
code allows for lots of variations to experiment with
in just about all of its sections. I'm afraid that the
long "fa.append" line got messed up by my email
system, but it should be easy to fix.
