Patterns That Never Repeat Themselves

Penrose tilings cover a flat surface using shapes that never create a repeating pattern. Even though they look structured, the design remains unique no matter how far you extend it across the plane.

Most geometric patterns rely on a grid that repeats perfectly, but these tilings use two specific shapes to defy such simple rules. Remarkably, these shapes feature fivefold symmetry, a geometry that is mathematically impossible to achieve with standard repeating grids. First discovered in the 1970s, these patterns were later found to exist naturally in the structure of exotic materials called quasicrystals. This discovery completely changed how scientists understand the order found within solid objects.
