/*
* Written 1997 Jens Ch. Restemeier <jrestemeier@currantbun.com>
* This program is based on an algorithm / article by
* Jörn Loviscach.
*
* It appeared in c't 10/95, page 326 and is called
* "Ausgewürfelt - Moderne Kunst algorithmisch erzeugen"
* (~modern art created with algorithms).
*
* It generates one main formula (the middle button) and 8 variations of it.
* If you select a variation it becomes the new main formula. If you
* press "OK" the main formula will be applied to the image.
