Stained glass artwork based on two overlapping golden spirals. One blue spiral originates in the lower left corner, spiraling inward connecting the corners of progressively smaller squares. The squares group together to form a golden rectangle based on the golden ratio (Phi). Therefore the spiral is a golden spiral. The second blue spiral starts in the upper right corner and it spirals inward following the corners of golden isosceles triangles. The golden ratio defines the ratio of the sides of the triangles. This second overlapping blue spiral is also golden.
