A sketch based off of the ubiquitous fractal tree (with the branching code borrowed from Daniel Shiffman's implementation).
The tree is rotated around to create a shape reminiscent of a flower, which blooms and folds back in repeatedly.
UP/DOWN control the number of petals in the flower (default is 4)
LEFT/RIGHT control the number of branches at each layer (default is 2)
