12. The Trial of Tilted Arc, 1985
Speaker after speaker who wanted the sculpture removed identified it with graffiti, lawlessness and even terrorism. The work was painted with epithets like ''nonsense,'' ''garbage,'' ''hideous,'' a ''calculated offense,'' the ''barrier that passes as art'' and the ''Berlin Wall of Foley Square.'' One person who works in the neighborhood asserted that the work was ''negative and useless. There is no idea, no humor, no education value, no nothing. It looks barren, it is barren.'' Another speaker said that ''there is nothing, nothing to justify the title of work of art in this piece of scrap iron, and that is all there is to it.''

26. Christo and Jeanne-Claude, Running Fence, Sonoma and Marin Counties, 1972-76

27. Running Fence, 5.5 meters (eighteen feet) high, 40 kilometers (twenty-four and half miles) long, extending East-West near Freeway 101, north of San Francisco, on the private properties of fifty-nine ranchers, following rolling hills and dropping down to the Pacific Ocean at Bodega Bay, was completed on September 10, 1976.
The art project consisted of: forty-two months of collaborative efforts, the ranchers' participation, eighteen public hearings, three sessions at the Superior Courts of California, the drafting of a four-hundred and fifty page Environmental Impact Report and the temporary use of hills, the sky and the Ocean.
All expenses for the temporary work of art were paid by Christo and Jeanne-Claude through the sale of studies, preparatory drawings and collages, scale models and original lithographs.
Running Fence was made of 200,000 square meters (2,222,222 square feet) of heavy woven white nylon fabric, hung from a steel cable strung between 2,050 steel poles (each: 6.4 meters / 21 feet long, 9 centimeters / 3 1/2 inches in diameter) embedded 1 meter (3 feet) into the ground, using no concrete and braced laterally with guy wires (145 kilometers (90 miles) of steel cable) and 14,000 earth anchors.
The top and bottom edges of the 2050 fabric panels were secured to the upper and lower cables by 350,000 hooks.

31. Christo and Jeanne-Claude, Surrounded Islands, Biscayne Bay, 1980-83
6.5 million square feet of floating pink fabric encircled eleven islands in Miami's Biscayne Bay, extending the perimeter of each island by 200 feet. Ultimately, the project benefited its surroundings: Christo and Jeanne-Claude's crew removed forty tons of garbage from the uninhabited islands.
As the unfurling began on 4 May 1983, the islands themselves seemed to bloom. Remaining on view for two weeks, the work was visible to the public from the causeways, the land, the water, and the air.

48. Nauman, Live/Taped Video Corridor, 1970
In the closed-circuit installation «Live/Taped Video Corridor», Nauman set two monitors above one another at the end of a corridor almost ten meters long and only 50 cm wide. The lower monitor features a videotape of the corridor. The uppermost monitor shows a closed-circuit tape recording of a camera at the entrance to the corridor, positioned at a height of about three meters. On entering the corridor and approaching the monitors, you quickly come under the area surveyed by the camera. But the closer you get to the monitor, the further you are from the camera, with the result that your image on the monitor becomes increasingly smaller. Another cause of irritation: you see yourself from behind. A person thus monitored suddenly slips into the role of someone monitoring their own activities.
