Sheryl Oring, assistant professor of art, seeks donations of vintage typewriters for a public performance, “Collective Memory,” to be held in New York City over the Sept. 11 weekend. Oring, who has a long history of creating interactive public art projects, is organizing a pool of 10 typists who will set up a public office from 12:30-2:30 p.m. on Sept. 9, 10 and 11 in Manhattan’s Bryant Park, 3½ miles from the World Trade Center site. Typists will ask park visitors a simple question: “What would you like the world to remember about 9/11?” Answers will be typed verbatim on small sheets of white paper and collected for use in a traveling exhibition that will visit college campuses. It will be part of the Department of Art Faculty Biennial at the Weatherspoon later this semester. She may be reached at firstname.lastname@example.org.
