There is a new temporary exhibit at the Smithsonian National Museum of Natural History. Margaret and Christine Wertheim, co-founders of The Institute for Figuring, combined mathematics with crochet to create a beautiful "underwater" land full of atolls and clusters of crocheted corals. Using yarn and other found materials their complex crocheting techniques gave shape to quite natural-looking forms.
While this is an "art" exhibit, it also encompasses a social project as noted on the Smithsonian website:
"The Hyperbolic Crochet Coral Reef is a traveling exhibition that not only displays these artworks, but also incorporates an ever-growing social project—teaching others around the world how to crochet hyperbolically and make their own reefs. By working through this process and viewing the art, one can see the correlation between the crocheted reefs and living corals, such as the Great Barrier Reef in Australia. The fragility of the coral reefs is echoed by their crocheted counterparts."
