Turtle Graphics

I first learned about Turtle Graphics when @winterchan inquired about the Harriss spiral:Generate the Harriss Fractal in this forum. When I researched it TurtleGraphics was one of the ways it was first drawn and I was impressed at how something so complicated could be drawn by something so simple. That technique inspired the work that I have posted here and has been ported to other languages: https://rosettacode.org/wiki/Harriss_Spiral , which brings me to my next question: Would you be able to draw a Harriss Fractal with your new creation?
