beat me to it... many is the hour and day wasted wwaiting for the next zoom level . i remember in the late 80's setting it off going to bed and seeing if it finished by morning... then zooming on somewhere interesting and going to work . marveling at what the image was after i got home.. those were the days ...Ah, the lesser spotted julia set!
Edit: Apparently the German for 'fractal' is 'fraktal'. It would be called a Mandelbrot set if it were a Mandelbrot but in this case it's not.
