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. This is version 2.1 an update to version 2.0. Binary only. Author: Gary Teachout
