The paving in front of the Andrew Wiles building is constructed from just two different diamond-shaped granite tiles, each adorned identically with stainless steel circular arcs. There are various ways of covering the infinite plane with them, matching the arcs. Every such pattern is non-repetitive and contains infinitely many exact copies.
