Presented paper at #puarl2016 conference in one of four parallel tracks. Audience ranged from newcomers to the body of work, through to a coauthor with Christopher Alexander of the original 1971 A Pattern Language book. About 100 attendees at this conference. USF is still lively on a Saturday with singing and music competing in the main room through a thin room partition wall. (Cowell Hall, University of San Francisco, California) 20161029
