Spiral

Below are three different types of spirals. Spirals exist in nature and man-made objects. The spiral galaxy and a seashell shown in the first two figures below are spiral shaped. The staircase is also in the shape of a spiral. The archimedian spiral and golden spiral are two well known 2D spirals. Archimedian spiral
