MACNA 2013 Video A live postcard from MACNA 2013 in South Florida, this short video by John Carlin catches the flavor of the exhibition hall, where startling corals, tiny cuttlefish and marine salesmanship vied for the attention of an estimated 2,500 attendees—a record turnout in the 25-year history of the event.
