Described as an interactive music installation, Grisha Coleman's Reach, Robot comprises dozens of blue lines strung over PPG Plaza in downtown Pittsburgh. Continually sensing the movement of passers-by, the network is hooked up to a sound system concealed in the plaza's central obelisk. At a level just subtle enough to register, ambient chimes murmur beneath the hubbub of one of America's busiest town squares. Here's a short clip of the audio, and Coleman explaining the work... The thought crossed my mind that when the robots rise, they could take out hundreds of meat units simply by lowering these cables a couple of feet and suddenly pulling them taut across the plaza.
