Dowload here the source code for bc Mandlebrot plotter [ZIP file]; start plotting using the command bc mandel.bc. The zip contains a makefile, it's only useful if you have the make program installed (else ignore it). If you also have the sed program, make color will do a nice color plot on an ANSI-color-capable terminal (true for most UNIX/Linux, usually false for Windows).
