You're right. If you could tell me such a program... I would have used
it. The nearest approximation was xfractint but it's cumbersome to use
and doesn't have a gradient editor (and I'm not sure whether it's
capable of rendering 20000x14000 pixel images). ;-)

Muhahaha. The printer took about 8 hours to RIP the precalculated stuff.
The Xeon/2.4GHz took about an hour to render the fractal. I thought
about that, but I'm not familiar with Postscript (I guess, the gradient
stuff would be the most complicated - I used a custom gradient).
Bye, Tino.
