After writing a program that draws something that looks like a tree, the next logical (??) step was to write a program that would create a small forest.
And here it is. You can also get it in a .DSK file, with a most of the programs from the site.
The program is very simple. After drawing a basic background, it picks some random paramteres that will define the size and shape of the tree, and call the routine from the "Fractree" program, slightly modified to give different colors to different parts of the tree.
