Goose smaller The blue geese in the spiral shrink by a square root factor of 2. 
Goose bigger and smaller The geese grow and shrink. 
Goose bigger The inspiration for this self similar tessellation comes from M.C. Escher's Square Limit woodcut. The structure of the image is here.

Deep Sea Fish At the fish mercado in Valencia. 
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" and "dart". Normally, such a tiling is shown with solid colored quadrilaterals having straight line segments, but here the kite is morphed into a parrot and the dart into a goose. The images are constructed by the substitution rule, so that the final shape resembles the shape of the initial quadrilaterals: the sun (5 kites), the star (5 darts) and a single kite. 
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. 
Buzzard & Kingfisher Aperiodic AmmannBeenker tessellation, third generation. Click here for the fourth generation. Normally, such a tiling is made with squares and rhombuses having straight line segments. In this tessellation, the square is transformed into a buzzard and the rhombus into a kingfisher.

Orange Blue Fish Loxodromes Along 8 loxodromic spirals the fish swim from north pole to south pole and in between the other fish swim in the opposite direction. With a bearing of almost 62 degrees the path equals about 6.67 times the radius of the sphere. 
Blue Green Fish Loxodromes The fish in between the other fish swim in the opposite direction. 
Four Colored Fish Loxodromes With a bearing of almost 62 degrees the path equals about 6.67 times the radius of the sphere. 
Seagull Loxodrome The birds fly along 11 loxodromic spirals from north pole to south pole with a bearing of about 50 degrees. 
Fish Sphere Surface This image of 8 loxodromic spirals is inspired by M.C. Escher's Sphere Surface. The construction is based on the paper of James Marcotte and Matthew Salomone.

Double Seagull Spirals This space filling tessellation of a double spiral is not fully symmetric. The bird escapes from the bottom spiral and disappears at the top spiral.Watch this animation (4.8Mb) 
Seagull Spiral This is a spiral with 19.373 seagulls per revolution in order to fit the tessellation. 
Seagull Circles This seems a spiral but they are only concentric circles of 19 seagulls, with a displacement to fit the tessellation. 
Parrot Spiral Space filling parrots tessellating in the form of a spiral. If you look through your eyelashes you see spirals of circles containing 6 parrots. 
Toucan Circles The concentric circles of toucan tessellations show spirals.
