The CFIll-suite of programs were originally written using C++ and QT for a talk I held at Cybercamp back in 2003. Later I also did similar talks at NTNU and at The Gathering.
In April 2007 I did a presentation of chaos at Math Circles at Washington University, and decided to rewrite my old programs using Java so I could make them more easily accesible.
As of now, I have rewritten the Web Diagram and (a limited version of the) Bifurcation programs, which are used to search for chaos in real equations. I hope to do the Mandelbrot and Julia set explorers as well some time soon.
Tips, comments, bug reports and other feedback is highly appreciated.
