Glow Sunflowers

The Sunflowers artwork at Glow, the yearly Light Art Festival in Eindhoven, is a homage to the famous Dutch painter Vincent van Gogh, who lived in this neighborhood for a few years. The image reflects a field with uncountable sunflowers.

P2 Penrose Sun

The aperiodic P2 Penrose tessellation is based on quadrilaterals called the "kite" (parrot) and "dart" (goose).

P2 Penrose Star

The images are constructed by the substitution rule, so that the final shape resembles the shape of the initial quadrilaterals: the sun (5 kites), and the star (5 darts).

P3 Penrose

This aperiodic P3 Penrose tessellation (seventh generation) is based on the thin and thick rhombus. Normally, such a tiling is shown with solid colored rhombuses having straight line segments.

The lithograph "Print Gallery" of M. C. Escher was the inspiration for this photo. The mathematics behind that print were unraveled and presented by H. Lenstra and B. de Smit. A variation of their formula was used to create my photo as a nowadays selfie.
