I was inspired the Sierpinski Triangle, and the result of my code is meant to be an abstracted version, with a similar idea. I wanted to challenge myself, so I was originally looking into ideas of recursion to draw the Sierpinski Triangle, along with the turtle graphics, but unfortunately after a while it went beyond what I was capable of. I chose to keep going with the idea, and abstract it, in the hope that sometime in the future I will learn (which I did), and possibly rework the code some day to make what I originally set out to. However, I think this is still a pretty interesting graphic. I commented out the first two meanders.
