This applet displays the Mandelbrot fractal set. Clicking on the image
will zoom in. The "Options" bar allows you to change the maximum number
of iterations, reset the image, or get help information. This applet
illustrates how an image can be periodically updated while it is being
Performance hints: the lower the maximum number of iterations,
the faster the computation. Also, the black region (the Mandelbrot set
itself) is the
slowest to compute, so if you zoom includes a lot of it, computation will

If you're looking for more information on fractals, I have reviews
of some fractal books.
