Hyperaurea: Equinox charts a course through Antarctica, the last frontier on Earth, as experienced by Sean Williams, Arts Fellowship expeditioner to Casey station in 2017, and palaeontologist Professor John Long. Ambient music (Williams) and hypnotic visuals (Katie Cavanagh and Shane Bevin) combine in two unique presentations: an intimate, fully-immersive ambisonic experience, and an open-air iteration in the natural amphitheatre of Flinders University’s Bedford Park campus.
