A paper strip is creased to form six rhombuses, each consisting of two equilateral triangles. The other side of the strip is shaded. At the top-left point of each rhombus, perform the fold-and-twist (F-A-T) algorithm (from left to right): fold over the larger diagonal and twist over the left side. The result is a regular hexagon. In 2D graphics, folding is equivalent to a reflection.
