The demo uses an axiom of "F+F+F+F" and a rule of "F -> F+F-F-FF+F+F-F". The program uses a turtle to interpret the data, whereby "F" draws a line to the next step based on the step size and current angle, "+" is an increment of the current angle and "-" is a decrement of the current angle, both by a fixed delta. The rule applied for a fixed number of iterations.
