Turtle Plots of Integer Sequences

摘要

"Turtle graphics" have been popularized as a paradigm for teaching programming to young children in elementary and middle schools. Here, we adopt the procedure to apply to integer sequences. The result is an association of a gray-level image, called Turtle Plot, to an integer sequence. This turned out to provide an interesting way to visualize and discover certain hidden behavior of integer sequences. We demonstrate how dragon and Levy C fractal curves can be obtained as Turtle plots easily.
