Artist Jody Zellen explores the collision of public and private space facilitated by mobile telephony in her latest work, 'Disembodied Voices.' Cell phones allow us to converse with each other anywhere, and the separate halves of our intimate conversations can become bizarre performances for audiences of innocent bystanders. Zellen describes the web site as 'a meditation on the nature of public space'; here you can listen to snatches of conversations in a number of languages, contribute a disruptive cell phone encounter story to the forum, and become another node in a translocal wireless network of callers. - Helen Varley Jamieson
