Using a single thread roughly 1-2 km long (0.6 – 1.2 mi), Petros Vrellis continuously wraps the thread in straight, continuous lines, from one peg to its direct opposite peg in a circular, 28″ loom with 200 evenly spaced anchor pegs on its circumference. Thus each artwork is made from 3,000 – 4,000 continuously intersecting straight lines of a single thread.
Interestingly, knitting is done by hand, with step-by-step instructions dictated by a computer algorithm designed by the new media artist. Vrellis explains:
“The pattern is generated from a specially designed algorithm, coded in openframeworks. The algorithm takes as input a digital photograph and outputs the knitting pattern. Over 2 billion calculations are needed to produce each pattern.”
For ‘inputs’, Vrellis used famous portraits by the famous Spanish Renaissance artist El Greco. Below you can see a timelapse video along with close-ups of Petros’ experimental knitting project.
