The Artist's Husband: The Secret Life of L-Systems
L-Systems can be used to draw plants! To make this work, we need to add some capabilities to our Turtle structure. Up until now turtles could either move ahead or turn. To draw plants, we need to be able to save a turtle state, do some drawing, and then move the turtle back to the saved state. This has the effect of magically teleporting the turtle to someplace it has already been, restoring its position, direction and color.
