This is my fractal java applet, version 2.1 (July 2007), compiled using Java 1.6u1. It computes the classic Mandelbrot fractal, with an iteration limit of 5000, as well as some of my own variations. It is multithreaded and non-blocking, so feel free to animate the colors and/or zoom in/out while calculating.

• To zoom in: drag left mouse button.
• To zoom out: click on 'back'
• To animate colors: click on 'cycle colors'
• To stop animation: click on 'stop'
• To recompute and redraw current viewport: click on 'redraw'
• Click on the combo boxes to change max iteration limit or which equation is used

If it doesn't work chances are good your java is out of date. Download the latest JRE from java.sun.com
