One Block Radius is fascinating:
"One Block Radius, a project of Brooklyn artists Christina Ray and Dave Mandl [known collaboratively as Glowlab], is an extensive psychogeographic survey of the block where New York’s New Museum of Contemporary Art will build a new 60,000 square foot facility beginning in late 2004. […]
While the block is bit-size in relation to the surrounding metropolis, the changes it is about to undergo are massive. One Block Radius plays with this idea of scale, aiming to zoom in and physically data-mine the tiny area for the amount of information one would normally find in a guide book for an entire city. This feature-rich urban record will include personal perspectives from diverse sources such as city workers, children, street performers, artists and architectural historians. Engaging a variety of tools and media such as blogs, video documentation, maps, field recordings and interviews, Glowlab will create a multi-layered portrait of the block as it has never been seen before (and will never be seen again)."
