The Transborder Immigrant Tool is a Border Disturbance Art Performance that discusses the physical and virtual limits of the U.S.–Mexico frontier. It was developed by the Electronic Disturbance Theater (EDT) with the funding of the Arts and Humanities Grant 2007–2008 at the University of California in San Diego. The project uses an inexpensive GPS-enabled cell phone and a custom piece of software, the Virtual Hiker Algorithm, to guide border crossers in the desert. The crossing of the U.S.–Mexico border can be deadly due to the severe conditions of the environment; once in the Mexican desert, the software installed in the cell phone directs the immigrant toward the nearest aid site, be that water, first aid or law enforcement, along with other contextual navigational information. According to the EDT, the Transborder Immigrant Tool was created with the aim of reappropriating widely available technology to be used as a form of humanitarian aid, as well as offering a tactical intervention of distraction and disturbance in the order of transnational corridors. In addition to the navigational capabilities of the Tool, the performative effect is also provided through poetry made available on the screen of the cell phone. It is with this poetry that the artists attempt to rescue a sense of hospitality and to alleviate the difficulties of the journey.
