Nature and artificiality lie at the heart of the work of Scottish artsits, Dalziel + Scullion. Sargassum, shown to great acclaim at the Venice Biennale in 1995, appeared like a mysterious pool of water held between two walls. The Gifted Child, projected onto a screen of glass, hung in the air like a full moon and displayed a synchronised swimmer going through her movement. Wing, a new commission, took as its starting point modern farming methods creating an unnerving environment.
