Slicer         A program for creating abstract art based on mathematical
               functions, such as the Mandelbrot set, Julia sets, and
               related abstractions (chaotic dynamical systems). Features
               include fast fixed or floating point arithmetic, many
               different functions, many computation options, many coloring
               and rendering options, batch mode, multi pass mode, and four
               dimensional navigation. The pictures it makes can be thought
               of as cross sections or "slices" revealing the insides of
               solid objects. Release 2.1. Author: Gary Teachout.
