Penrose Til
Penrose Tiles
Penrose was not the first to discover aperiodic tilings, but his is probably the most well-known. In its simplest form, it consists of 36- and 72-degree rhombi, with "matching rules" forcing the
rhombi to line up against each other only in certain patterns. It can also be formed by tiles in ... | {"url":"http://www.ics.uci.edu/~eppstein/junkyard/penrose.html","timestamp":"2014-04-16T04:23:03Z","content_type":null,"content_length":"8908","record_id":"<urn:uuid:3a6a4d24-d2ba-4aed-8c9e-b5387ac17659>","cc-path":"CC-MAIN-2014-15/segments/1398223203422.8/warc/CC-MAIN-20140423032003-00416-ip-10-147-4-33.ec2.internal.w... |
