Looking at patterns in a modular way , much like wallpaper, is only a partial investigation. The complexities of overlapping elements goes far beyond a singular pattern repeated, however looking at the variation in patterns that come from one set of points is fascinating. Here a set 16 points have been set as two squares at 45 degrees to each other, an extracted part of the geometric scheme for the Dome of the Rock. This is just a selection of 12 patterns which use this geometric scheme but is by no means near a definitive list of possibilities. This should also be thought considered if a modular structural system is used and how many layout possibilities still remain.
