## Fun with an HP 7475 Plotter

So I got an HP 7475 Plotter used. I’ve been playing with it using a Python library called Chiplotle.

Recently I’ve been making fractals on it. Here’s a Hilbert curve I made:

Hilbert curves are space filling fractal curves. This means that when iterated to infinity, at no point is there a straight line; thus it is a curve. Very neat!

In order to get this to work, I wrote a turtle graphics class for the Chiplotle library. If anyone finds this useful, you can grab the code here.

Oh, and here’s a Sierpinski triangle:
