i’ve found this:
Beginning on May 20, 2011 the Museum of Contemporary Art (MOCA) in Los Angeles, California will be the site of Art Un-Scene, an exhibition of street art in Augmented Reality (AR). Street artists and graffiti writers worldwide are invited to submit digital photographs of their work, which will be uploaded into AR-space around MOCA’s location for public viewing.
The exhibition will be “hidden in plain sight,” invisible to the unaided eye, and can only be viewed using a modern smartphone (iPhone, iPad2 or various Android devices) and the Layar Augmented Reality Browser app. The AR exhibition will run in parallel with MOCA’s curated “Art in the Streets” show, but MOCA is not involved in any way with this event. We hope and intend that this AR exhibition will add much needed breadth and depth to the “official” story of street art that is being offered by MOCA’s curators.
Artists who want to learn more about the Art Un-Scene exhibition and submit images of their work should visit the website http://spacelib.org/unscene and email their images of work in any medium to: spaceliberation@gmail.com along with links to websites where more work can be seen, if available.
Art Un-Scene is being produced by the Space Liberation Movement, with in-kind assistance from Layar BV.
