This work is based on M.C. Escher's woven ribbon motifs, 1938, 1942. He's made wooden stamps for the basic motifs, and rotated and combined them to create fantastic woven fabric patterns. I've simply taken his idea a step further using combinatorics. Please note, this is a Fontstruct rendering, and as such may differ from the original.
