A unique tribute to nature, Fujiko Nakaya’s interactive work, fondly known as “the fog sculpture”, is described by the artist as “an ever-changing form, moulded by the atmosphere and sculpted by wind from moment to moment”. Since 1982, visitors to the National Gallery of Australia’s Sculpture Garden have been offered an experience of nature’s delicate balance. From 12.30pm to 2pm daily, 900 nozzles and a pump create a fine mist of water that wafts across the pond and circulates through the surrounding vegetation. The humidity of the fog reactivates the natural environment, thickening the foliage and cultivating new species – a self-sustaining ecosphere in Canberra’s harsh conditions.
