anglebase: angle that tree branch dividing is based around lengthbase: scales the tree levelnumber: how many divisions to make; more divisions mean slower drawing; after 8, tree drawing is not almost instantaneous. anglerandomness: how much the division angles vary (in degrees) lengthrandomness: how much the length of the branches varies (in steps)
Not using turbo mode results in very mesmerizing drawing that is nice to look at. Enable turbo mode by holding shift and clicking the green flag. Having an very big anglebase, lengthbase, or levelnumber will probably cause the tree to hit the edge of the window. This breaks the tree and causes it to look like a complete jumble. I originally saw this idea at Coder Dojo in Seattle. I decided to replicate it with a bunch of sliders for the variables and with controllable randomness.
