New Zealand collective Et Al. are known for their moody installations linking art, technology, political ideologies, scientific theories, fringe religious practices, and Cold-War-style behaviour modification. the second of the ordinary practices develops out of their 2005 Venice Biennale project, the fundamental practice. Recorded and computer-generated voices read extremist texts from within five crudely constructed APUs (autonomous purification units). Resembling sentry boxes and orgone accumulators, the APUs move back and forth on wires behind cyclone-fencing enclosures. We don’t know if they are the prisoners or the warders. Their purpose—malicious or benevolent—remains unfathomable. An adjacent computer control room includes a video projection of an aerial view of Baxter Internment Camp, a live feed from Google Earth. Superimposed on this scene like giant obelisks are five stylised APUs.
