DIY urban reclamation

Heavy Trash, an LA public art collective, takes direct action against gated communities by offering the public a way to view (or maybe snipe at) them:

Like the historic viewing platforms at the Berlin Wall that allowed Westerners to see into East Berlin, the Heavy Trash viewing platforms call attention to the walls of gated communities and provide visual access to parts of the city that have been cut off from the public domain.

Their earlier one-ton metal access stair to grant the public access to a fenced-off park is just brilliant.
