“Tree Growth” is a very simple piece that I find really intriguing. Like Alyssa mentions, the process of painting a tree comes down a lot to muscle memory and random brushstrokes to give it enough “noise” to be lifelike. This program does the exact same thing, replicating the process of painting or growing a tree through computational means.
The leaves even change color by the seasons! The piece, fundamentally, is simulating natural growth within the confines of code. By roughly replicating the natural process, the piece takes the first step towards growing a “real” digital tree.
