"Through an unlikely fusion of mathematics, marine biology, handicraft and collective art practice, the Wertheims and their contributors produce large-scale coralline landscapes both beautiful and blighted."
"Anchored in the fields of both ecology and geometry, the Crochet Reef began in 2005, when – in response to devastation on the Great Barrier Reef in their native state of Queensland – the Wertheims conceived of constructing an artificial reef, based on the fact that corals, kelps and other sea creatures are biological incarnations of hyperbolic geometry, an alternative to the usual Euclidean variety."
