Dragon Curve

In this example, we use turtle graphics to generate fractals.

The curve is generated from a self-similar sequence of left and right turns. The basic pattern is :

dragon(0) -> R

dragon(1) -> dragon(0) + R + inverse(dragon(0) -> RRL

dragon(2) -> dragon(0) + R + inverse(dragon(0) -> RRL

and so on. You find a detailed description on Dragon Curve (Wikipedia)

.. literalinclude:: dragon.py

generate the curve for a small depth first
if the size parameter is too big, the program will crash because it reaches the array boundaries.

Try the following self-similar sequence:

:::text
seq(0) -> LRRL
seq(1) -> seq(0) + L + seq(0) + R + seq(0) + R + seq(0) + L + seq(0)
