Museum ups security to show Chris Burden's Tower of Power gold bar sculpture

Chris Burden’s Tower of Power gold bar sculpture, from 1985, and on show in the artist’s retrospective at the New Museum in New York, will have its own 24-hour security guard, the Guardian reports. The work consists of 100 kilograms of gold ingots, (worth about £2.6m) stacked in a pyramid within a vitrine. Tiny figures made of matchsticks and sewing needles encircle the tower.
