Colossus: Three 8-ton boulders are suspended under massive metal arms, with
ropes dangling from them that allow participants to spin the entire 50,000-pound, 7-story contraption -- if they really
pull. The resulting motion can be seen from quite some distance away. The artist, Zachary Coffin, had
previously made another art piece involving huge suspended boulders: the Temple of Gravity.
