Check out the crocheted coral reefs I found in NYU windows on 10th and Broadway. They’re part of the Hyperbolic Crochet Coral Reef exhibit meant to call attention the environmental problems surrounding the Coral Reefs.

More information, including lots of pictures about the process, are here on The Institute for Figuring web-site. Or you can read an article about the crocheters at nytimes.com. Or you can check out the reef replicas in real-life in the NYU windows or at the World Financial Center until April 18, 2008.

“As it turns out, the gorgeously crenellated, warped and undulating corals, anemones, kelps, sponges, nudibranchs, flatworms and slugs that live in the reef have what are known as hyperbolic geometric structures: shapes that mathematicians, until recently, thought did not exist outside of the human imagination” (NYTimes.com).
