This decagonal flower is based on the pattern from August 8th (which uses nonagons--nine sided polygons instead of ten). The decagons are arranged in a back and forth loop and then the triangles were inserted in a zig-zag pattern to form the inner loop. The rest of the pattern, the outside, was added as decoration. Notice that there is a bit of conflict of rotation. It seems that the ten gaps seem to infuse a of a counter spin into normal spin of the inner loop.
