In 1974, Roger Penrose showed that if you fill those gaps with three more shapes, a five-pointed star, a ‘boat’ that is three-fifths of a star, and a thin diamond, the result covers the plane forever without repeating.\u003c\/p\u003e\n\u003cp\u003eThe process to generate a tiling is recursive: Split every pentagon into six smaller ones, fill the gaps by the same rule, and the whole tiling can rebuild itself one size smaller.\u003c\/p\u003e\n\u003cp\u003eNever-repeating tilings are important puzzles in computation, too: no computer program can always tell whether a given set of tiles will cover an endless floor; a geometric version of the halting problem.\u003c\/p\u003e\n\u003cp\u003eEven simple rules can result in extraordinary complexity: Some tiles can fit together to cover a floor forever, but only if the pattern never repeats.
