I Programmed A Pen Plotter To Draw Portraits With Circles And Triangles

In my free time, I program my plotter Karel to draw illustrations. Here are two examples of his styles. Portraits made of only circles or triangles. I love using simple shapes in my work and creating complex drawings a collection of the most simple things.
The drawings are drawn with a simple sharpie marker and Karel takes a little bit more than one hour to finish those.
