Travel-based net art was big in the early days, with projects such as Arctic Circle, Siberian Deal, and Communication Creates Conflict layering international travel with web site navigation. www.tropisms.org is a recently launched travelogue and vlog. (Vlogs are like regular blogs, but feature video as well as text and images). With lively graphics, the site's videos document the seemingly random travels of Dutch filmmakers Jan de Bruin and Luuk Bouwman in South America. The duo touch on some critical media issues in Peru and Bolivia, and as a platform for footage from South America, and a sample of vlogging, www.tropisms.org is worth a visit. -- Rachel Greene
