About this Product
Science meets art. The double helix is a beautiful structure and in this case a Girih tile pentagon is used for the model. Girih tiles appear in Islamic architecture dating back to about the 12th century and appear to be generated using only a straight edge and a compass. More details on the intricate geometric patterns that can be generated with these tiles can be found in Wikipedia.
