Launching today is 'Packet,' a new online exhibition space that takes its name from the packets of data that whiz round the internet and are reassembled at the end of their journey into a greater whole. 'Packet' will provide a stepping-stone space for students and artists new to digital media who haven't yet developed enough work for a full show. Exhibitions will change monthly, with the first artist being Roberto Pasang, followed by Johnny Liu in February and Kimberly Turner in March. Packet is an initiative of San Francisco gallery New Langton Arts. -Helen Varley Jamieson
