Driven Pendulum Simulation.
This simulation was inspired by "Chaotic Dynamics, an introduction" by
G.L.Baker and J.P.Gollub.
The fractal explorer is based on a description given by Peitgen and Richter in their book "The Beauty of Fractals"
Iterated Function Systems
In his book "Fractals, a very short introduction", Kenneth Falconer describes how to draw the fractal defined by an
iterated function system (IFS). This method was introduced by Michael Barnsley, and is a kind of random walk.
On the IFS page you can view some standard examples, or enter your own coefficients.
