The Center for Locative Media works with different cultural and educational communities to enable the creation, delivery, and distribution of narrative histories of people and places using emerging and locative technologies.
To date, the Locative Media space has primarily been inhabited by artists. But as educators and amateur neo-geographers, we found a rich vein of place-based pedagogy to tap into. Here story was already married to place. As technologists we watched the tools become available to not only tag content to place, but to experience it in that place.
Locative Media, like its technology, is emerging; but as with all community engagement, it has its roots in the the importance of story, the value of place, and the use of technologies old and new."
This website seems to pretty useful, it has tons of different examples of locative media work. Thought i would post a couple of them below,

It also has another couple decent links, one that is about the tech that is around at the moment.
