An ever-evolving nature-culture hybrid created by Margaret and Christine Wertheim, the Crochet Coral Reef resides at the nexus of art, science, mathematics, community practice and climate change.

Art + Science

Created as an artistic response to global warming and oceanic plastic trash, the Crochet Coral Reef also invokes hyperbolic geometry and Darwinian evolution.

Satellite Reefs

The Crochet Reef sends out spawn. 40+ community-based Satellite Reefs have been made around the world. During COVID lockdown, 3 new Satellites are underway – in Finland, Canada and Illinois.


“The sculptures are like force-fields drawing you into their orbit, catalysts for a network of social relations that mimic a reef’s … Gorgeous, absurd and socially productive, these are rare works of art.”

— Christopher Knight, Los Angeles Times

“The Crochet Coral Reef risks making real and fabulated things together to open up still-possible times for flourishing … Palpable, polymorphous, terrifying and inspiring stitchery… ”

—Donna Haraway
