Processing: Creative Coding and Computational Art

Obviously, there are a lot of things I could still do with the tree code, but hopefully one of
you will eventually take the code and improve upon it. I hope I was able to illustrate in this
example how you can play with the code and even find stuff in the process of coding. Yes,
there is some thinking involved, but there is also a lot of play and discovery. I’ve included
the entire tree program following, with code comments for your hacking pleasure. If you
want to try running this, launch Processing and type (or paste) the code into the
Processing text editor.
