Not too long ago I came across a piece of art made by Petros Vrellis. A piece of art that makes the engineer in me scream: automation. As can be seen below Petros uses a circular loom and a lot of patience to develop portraits from thread. Below I'll quickly go through the steps of automating the process but of course all the credits go to the artist behind this amazing idea! The final result is a halftone representation of an image using nothing but thread.
