This festival has already passed, but it was unique and a huge success all around. Locative media allows for direct responsive interaction with the urban environment. Please see People page to read about the artists involved and check out the projects. There were some complex urban planning/design approaches to utilizing mapping, for example, registering all kinds of urban data and GAFFTA, hosting gallery, opened with a retrospective of data visualization by MIT Senseable Cities lab - they have incredible resources. It would be interesting to hear some responses to 'urban data' as a political idea from progressive urban planners and designers/thinkers.
