Changes tree into various important fractals, from rectangular heat sink to trees, snowflakes, to triangle. With 3 splits, you can get, a fractal triangle: set angle to 120, lower angles for fractal tree. That's with shrink factor of 0.5 2 splits and angle = 90, shrink between 0.6 and 0.7 makes a rectangular fractal as used in heat sinks.
