An applet for playing around with WikiPedia:Mandelbrot_set of varying exponents. An exponent of 2 is the most common one, but higher ones -although slower to calculate- also generate interesting images.

The UI controls are functional while an image is drawn; you don't have to wait until it's done. Clicking on the "Approximation: On/Off" label toggles approximation mode, which shows an increasingly finegrained approximation of the final image. This is useful to get a first idea of what an image looks like, and zoom/pan without having to wait for the whole image to be finished.

The source code can be found here. This is some of the earliest Java code I ever wrote, so the code quality is not really what I would like it to be nowadays :-)

You must turn on Java for applets to work.
