Clean-up! Sculpture in aisle nine! | Metafilter
: "I recall a legendary guerilla art installation put up in the middle of the night in (I believe) Northampton, Mass: a television playing a video loop of something disturbing to the public decorum ( like a talking head proclaiming the advent of Orwell's 1984, or some such )was bolted 8 or 10 feet up on the side of a building on Main Street. A metal cage over the TV prevented easy removal, especially because the contraption was rigged to throw off showers of sparks if disturbed. It sucked power off a line coming directly from a pole. The fire and police depts. eventually gave up and called the electric company to cut the line. It was quite a public spectacle.
That's good art too."
