Heritage Council chair Stephen Davies is unable to issue a stop work order against the Opera House advertising projections of Racing NSW because light does not cause physical harm. Instead The Chaser projected Alan Jones’s phone number on the Supreme Court and NSW parliament from a moving car, while citizens disrupted the racing ads with torches. This David and Goliath contestation of public space has a fascinating history. In 1894 the Melbourne Salvation Army was just as aggressive as Racing NSW, but for the cause of Temperance. They used the latest limelight powered magic lantern to obliterate a schnapps ad on the side of a pub with a projection of Jesus and images from ‘The Rock of Ages’, while their band played hymns.
While light does no physical harm, as anyone who works with projection knows, it completely redefines space, transforms mood, and rewrites meaning. The act of projecting on a building is strangely exhilarating, because a small act is ‘projected’, not just optically by the lens, but semiotically by the stored symbolic power of the building.
Heritage values are created by lighting. Think of how the warm tungsten lights, which nightly bathe the newly cleaned sandstone facades of the public precincts of virtually all the world’s cities, have reshaped our mental image of those cities. And they can be destroyed by lighting. Fortunately, in the optical arms race, guerrilla action can still outgun the big boys.
