(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().
