In the 1970s, artist Don ZanFagna conceived the idea of a home created, constructed, and maintained by all-organic processes in complete harmony with nature. For the next 25 years, he explored this idea through writings, drawings, photographs, and models, many of which will be on display at this exhibition. Stop by the gallery on the 19th from 5-7 p.m. for the opening reception. The Halsey Institute, 161 Calhoun St. Monday-Saturday, 11am-4pm. Free. (843)953-4422, www.halsey.cofc.edu
