Artist Heath Bunting turns border hack in \_BorderXing Guide\_, the newest installment in the Tate Modern's Net Art initiative. Bunting crossed numerous international borders unfettered , and the site documents his treks. On top of its intentions to comment on how travel is restricted by politically and economically-motivated bureaucracies, the project's accessibility is itself controlled: users must submit a static IP address to function as an authorized client or log in from a preapproved terminal. Waiting for approval may seem as much fun as standing in line for a passport stamp, but what gets revealed will reward your patience.
