Tree using recursion

A big tree can be drawn by putting together a few little trees, and a little tree can be made out of tiny trees. By making a tree function with a size argument, we can make a tree out of smaller trees. Consider something like speed 10 for faster drawing.

Organic Shapes using randomness

The tree is made of smaller trees, each 3/4 as large as the big tree. In nature, shapes are not perfectly sized. Investigate the random function, and try varying the ratio so that instead of 3/4 it is random number less than 1.
