Pinwheel tiling is a form of aperiodic tiling, which means it can cover a plane without repeating patterns while still being composed of simple geometric shapes. Specifically, pinwheel tiling uses a set of shapes known as "pinwheels" and is notable for its ability to create complex patterns that do not exhibit translational symmetry. The concept of pinwheel tiling was introduced by mathematician Robert Ammann in the 1970s.
