Diagram for Conical intersect by Gordon Matta-Clark, 1975
Gordon Matta-Clark (1943 - 1978) was a New York artist famous for discovering – then purchasing – fifteen slivers of land peeled off NYC’s grid that came to be as a result of glitches in surveying, rezoning, or redevelopment. Matta-Clark died before bringing his creative collection to light but his work was rediscovered in the early 1990s and exhibited in collage form in 2005. Described as a "schematic drawing of the lots," all 15 were compared using uniform scale.
