If we consider the equation f(z) = z^3 - 1 for complex z, we recall that are three solutions to this equation, the three cube
roots of 1. We will start with any point in the complex plane and
then we will use the Newton-Raphson technique to determine which
of the three solutions this technique converges to. Every point
which converges by this method to z=1 will be colored red. The points
which converge to the other two roots will be colored green and blue respectively.
This will create three basins of attraction in the three colors.
The result is an unexpected surprise.
