+(Needs version 1.1 of the turtle module that
+comes with Python 3.1)
+
+Dancing turtles have a compound shape
+consisting of a series of triangles of
+decreasing size.
+
+Turtles march along a circle while rotating
+pairwise in opposite direction, with one
+exception. Does that breaking of symmetry
+enhance the attractiveness of the example?
+
+Press any key to stop the animation.
+
+Technically: demonstrates use of compound
+shapes, transformation of shapes as well as
+cloning turtles. The animation is
+controlled through update().
