I thought this might be a useful tutorial for some.

I've used Tierazon but I've found an easier way in Xaos. Clicking on Calculation>fast julia brings up a second window with a julia set who's seeds are 0,0. If you click around the edge of the Mandelbrot you can see the julia change. When you've found the one you are looking for just select fractal and uncheck Mandelbrot mode and you will be offered the seeds for this julia. Click on OK. After applying smoothing and antialiasing or any other filters you want to use you can save the image and gimp it.
