-This one draws spinning, animating (are you detecting a pattern here
-yet?) explorations of the Julia set. You've probably seen static
-images of this fractal form before, but it's a lot of fun to watch in
-motion as well. One interesting thing is that there is a small
-swinging dot passing in front of the image, which indicates the
-control point from which the rest of the image was generated.
