each time you click flag, a new tree will be formed. no two trees are the same, making endless varireties. I am planning to make different types of trees, some weirder than others. LOGS! Released: v1.0: release. do I need to explain any further? v1.1: branch drooping. v1.1.1: improved drooping physics. Planned: v1.2: new tree!
inspired by pusheen4robot's "3d tree" project.
