If anyone is confused as to the difference between the Mandelbrot set and a Fractal (We're not all mathematicians or programmers here) the two Wikipedia links below may help:

Used to spend way too much time on my DX4-120 doing fractals, but never on my CPC. The effect is super nice!
Yeah, I remember FractInt on the PC... great program. And astonishingly fast given that a Mandelbrot took about 40 minutes on the CPC in MODE 1, even in machine code.
Matthias Uphoff's Appleman program had the main routine in machine code:

Oh damn, FractInt indeed... soooo many hours (and CPU cycles) wasted!
