JoeBartholomew.com Scaling Girih Tiles
the scaling girih tiles projects are inspired by a remarkable Islamic art patterning system that originated by the year 1200, and was rediscovered by Peter J. Lu [1] in 2005. Islamic artisans used girih [2], from the Persian word for "knot", to develop intricate patterns from just five tiles decorated with lines. The lines rather than the tile edges become the pattern.
