Description: A fractal rosette of Penrose kites, quadrilaterals with angles 72°, 72°, 72°, 144°. These rosettes are not Penrose tilings, and can be formed for any kite for which one apex angle and the side angle sum to 180°(1-1/n), for some n; here n=5. For more on these rosettes, see Fathauer, Robert (2018), "Art and recreational math based on kite-tiling rosettes", in Torrence, Eve; Torrence, Bruce; Séquin, Carlo; Fenyvesi, Kristóf (eds.), Proceedings of Bridges 2018: Mathematics, Art, Music, Architecture, Education, Culture, Phoenix, Arizona: Tessellations Publishing, pp. 15–22, https://archive.bridgesmathart.org/2018/bridges2018-15.html
