Cut every wide and narrow diamond along a few set lines, and the pieces, scaled down by the golden ratio, join up with their neighbors' pieces into smaller wide and narrow diamonds: a finer tiling of the same sort. Do it again and again and the pattern gets finer and finer.\u003c\/p\u003e\n\u003cp\u003eLook closely at any large diamond and you will find the same tiling, one size smaller: chambers within chambers.\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.
