Abstract: A surface covering formed by planar components includes a plurality of concentric rings with each ring formed by corner components having two pairs of parallel sides of different length. The shorter sides of the pairs of parallel sides meeting at an angle equal to an angle formed by adjacent sides of a regular polygon. While the longer sides of the pairs of parallel sides meet at an angle equal to an angle formed by adjacent sides of the regular polygon. Planar infill components are utilized between the corner components with adjacent polygonal rings varying in size by a whole number of infill components. Spacing elements may be disposed between adjacent concentric polygonal rings.
