The Hyperbolic Crochet Coral Reef is an exhibit where "mathematics, marine biology, handicraft and community art practice all intersect. The project responds to the environmental crisis of global warming and the escalating problem of oceanic plastic trash."
The idea was created in 2005 by sisters Margaret and Christine Wertheim in their Los Angeles living room. Since the the idea has spread worldwide, thousands of crocheters send in their pieces to be part of the reefs. The exhibit is currently on display in Dublin as well as at the Copper Hewitt Museum in NYC.
Look at photos of the contributed crocheted pieces before the exhibit becomes assembled.
