Swirl Without End is a large Baravelle Spiral, which is defined as ‘a straight line design based on connecting consecutive mid-points of sides of regular polygons’. The spiral appears to curve round but there are no curves. It is made entirely from straight lines which make up triangles and squares. Each of the four arms of the spiral is made up from the same series of shapes, which fit round each other. The final triangles are truncated to create the overall octagon shape but the design could continue to infinity.
