The Highly Unlikely Square and Triangle are based upon the optical illusion known as the impossible triangle of Roger Penrose, made popular by M.C. Escher in the 1950s. The Swedish artist Oscar Reutersvärd drew the first impossible triangle in 1934. These little beaded objects look nice strung on a piece of cord or chain to be work as a small pendant. I have a tutorial for the Highly Unlikely Triangle, if you would like to learn to make one yourself. Or, if you want to just have one and not make one, all of these pieces are for sale in my Etsy shop. Click on the photos to go to the listings. As always, thank for looking!
