Palm Pilots and cell phones are quickly becoming venues for portable art. And cultural theorists are beginning to analyze how and why we use such nomadic devices. A just-opened online exhibition entitled "(re)distributions" (on view through October 31) is one of the first international shows to examine the new genres of handheld and wireless art. "(re)distributions" includes work by both established new media and Net artists and up and coming talent, as well as thought-provoking essays by leading scholars on PDAs and mobile phones and how they affect our lives and our culture.
