Really interesting talk by Margaret Wertheim of The Institute of Figuring. She discusses her project that recreates coral reefs by way of crochet techniques. Using the principle of hyperbolic geometry she gives life to a theory that was thought to have no tangible representation. She also proposes the idea of 'play tanks,' much like a think tank, but one in which we go beyond the cerebral masturbation, and get our hands dirty. Great talk.
