The traditional Fulani wedding blanket is woven primarily from camel hair. The weavers who created it say that spiritual energy is woven into the pattern and that each successive iteration shows an increase in this energy. Releasing this energy is spiritually dangerous; the weavers say that if they were to stop in the middle (where the pattern is most dense, and hence the spiritual energy is greatest) they would risk death. The engaged couple must bring the weaver food and kola nuts to keep him awake until it is finished.

Note that the first iteration has only two diamond shapes on each side, but the second has four. How is that acheived in the simulation?
