FracTree 1.0 is a program to design and draw fractal trees and
other fractal patterns in various stages of growth. Images can
be viewed on the screen, saved as bitmaps, or printed out.
This program is based on a string rewriting system, L systems
or Lindenmayer systems. You need Microsoft Windows 3.1 (or later)
to run this program which is shareware.
