However, looking at a mammal, we'd spot a mix-and-match right away. A drawing of a parrot would have a lot of flexibility, because our vague memory makes so many variations acceptable. Think about it: you know what a parrot looks like, but can you remember whether its tail is square or round? Are its wings long or short? I don't remember either. Unless you were a bird expert, you probably wouldn't notice the wrong beak on an eagle, or a long round tail that should be short and square. ![]() Unless the artist says "this is a yellow-crested sand diving beach warbler", the artist has a lot of freedom to mix and match body parts from several species. Draw the shape of the original tessellation that you want to rotate. There are no finicky rigid parts that stick out like the spines on a porcupine or the antlers on a jackalope. As long as a shape or pattern has two adjacent sides that are congruent, a rotation tessellation can be produced. That's not the only reason, or even the best reason. The most common tessellations today are floor tilings, using square, rectangular, hexagonal, or other shapes of ceramic tile, but many more tessellations were discussed in the Tessellations by Polygons chapter. ![]() Their wings can arc forward or back, or be held out straight. A tessellation, or tiling, is a division of the plane into figures called tiles. Their necks are sometimes as long and snake-like as an eel. However, they can be posed with no wing, one wing, or both extended the feet can be down or folded against their body. ![]() Escher based his patterns on congruent polygons that tessellate the plane. Why are birds a popular theme? They're not quite as flexible as fish and gym socks. directions produce a pattern with trans- lation and rotation symmetries. Almost all of us have done a bird design. When you choose a motif for your tessellation, choose something exotic with a shape that's got vagueness, variety, and flexibility.īirds are a very popular theme amongst tessellation artists.
