#
# Keith Vetter 2003-03-21: this started out as a simple little program
# but was so much fun that it grew and grew. So I apologize about the
# size but I just couldn't resist sharing it.
#
# This is a whizzlet that does a Rube Goldberg type animation, the
# design of which comes from an New Years e-card from IncrediMail.
# That version had nice sound effects which I eschewed. On the other
# hand, that version was in black and white (actually dark blue and
# light blue) and this one is fully colorized.
#
# One thing I learned from this project is that drawing filled complex
# objects on a canvas is really hard. More often than not I had to
# draw each item twice--once with the desired fill color but no
# outline, and once with no fill but with the outline. Another trick
# is erasing by drawing with the background color. Having a flood fill
# command would have been extremely helpful.
#
# Two wiki pages were extremely helpful: Drawing rounded rectangles
# which I generalized into Drawing rounded polygons, and regular
# polygons which allowed me to convert ovals and arcs into polygons
# which could then be rotated (see Canvas Rotation). I also wrote
# Named Colors to aid in the color selection.
#
# I could comment on the code, but it's just 26 state machines with
# lots of canvas create and move calls.
