Dynamics is a program written to illustrate the connection between Julia Sets and the Mandelbrot Set. It can draw magnified portions of the Mandelbrot set fairly rapidly, although it uses no clever mathematical ideas to speed drawing.
The source code is included. Mandelbrot drawing is performed by a single small method call, and readers are encouraged to optimize for the velocity engine separate the calculation into smaller tasks for optimization on multiprocessor machines. Dynamics is distributed under the GPL public license, and thus free.
