The Halsey Institute in Charleston will present this unique exhibit from the artist duo of Nate Larson and Marni Shindelman. Using publicly accessible geographic data from Tweets, the pair track down the specific location Twitter users were when they posted on social media. A photograph from the location connects the Tweet to the physical world. The work explores the dynamics between text and images, private versus public, and digital and analog. Halsey Institute of Contemporary Art, 161 Calhoun St., Charleston. Visit website for current hours. Free. (843) 953-4422, www.halsey.cofc.edu
