Crochet Coral Reef

Join a global art project that combines community activism, environmental awareness, math and science

Crochet has an amazing ability to model the mathematically unique forms of reefs while bringing crafting communities and science education together. That’s what inspired science writer Margaret Wertheim and artist Christine Wertheim, twin sisters from Australia, to create the Crochet Coral Reef project. 

Since the sisters started the project in 2005, more than 10,000 people from around the world have come together to crochet 40-plus community-made Satellite Reefs. Meanwhile, the Wertheims’ Crochet Coral Reef  travelling exhibition has delighted audiences from the Venice Biennale to the Smithsonian’s National Museum of Natural History in Washington, D.C.

The Ontario Science Centre is honoured to become the home of the Ontario Satellite Reef—building both a virtual reef as part of an online community and a physical art installation that will simulate a coral reef on the floor of the Centre. Complementing this citizen-art, the Crochet Coral Reef  travelling exhibition is scheduled to come to the Ontario Science Centre in late 2020.
