Machine drawings

Tristan Perich figured out a cool way of drawing fractal structures. A pen is suspended on a cable with two motors acting on its extremities. His algorithm drives the motors, which in turn move the pen on the canvas, forming a primitive plotter. Actually, before personal computers became widely available, a generation of algorithmic artists created their art using (professional) plotters.

His results are quite interesting. It is clear that the families of straight lines (or rather of arcs of circles) are drawn by acting on a single motor. The fractal clouds are probably obtained by making the motors move randomly in either direction, producing a random walk of the pen on the paper.
