The latest issue of Leonardo focuses on locative media. Quite a few worthwhile articles, including Leslie Sharp's "Swimming in the Grey Zones: Locating the Other Spaces in Mobile Art." Sharp discusses, among other things, a couple of ghost narratives she's working on:

The 'ghost' is one of those liminal forms that raises questions about embodiment and subjectivity and has a peculiar affinity to being picked up by the machines of technology. In the project for the Cheonggyecheon in Seoul, I am creating four separate narratives using night-vision and other footage shot on location in Seoul. In the narrative, the ghost is dug up by well-intentioned development, stirring up memories of place, colonization, and a Brechtian world of grey markets and grey activity. This ghost also inhabits streams – streams that flow down from the mountains and streams of data, searching for places to rest or to haunt, looking for things to play with and taunt. In particular, this ghost longs to haunt our devices of transmission, to produce in these devices an abject space that is uncomfortably close to our bodies. Ghosts are often mischievous; here the ghost also wants to play with errors of signal inaccuracy produced by satellites (usually compensated for by differential error cancellation in GPS), or to get the user to confuse the GPS to produce moments of dis-location.

The ghost itself is always an abject thing – signifying the cast off and suffering. This abjection can spill into the form or space it inhabits, creating a new monstrous space. I have written elsewhere about data space as a new monstrous [16]; in the case of the ghost, the monstrous is conjured by machines of vision and sound and varies according to the nature or properties of transmission: spirit photographs of the nineteenth century, or early telephones and radio seen as the 'devil’s instruments', recent technologies such as night-vision cameras that detect the undetectable, or technologies of transmission that transfer the formless as data and signals.
