Hyperbolic Plane

In 2005, I attended the talk "Crocheting the Hyperbolic Plane: A Talk by David Henderson and Daina Taimina" at The Kitchen and was blown away. The coral reef project has and continues to make its rounds.
I was doing a lot of crocheting at the time, especially tapestry crochet and tunisian crochet, enjoying the new possiblities of the craft. Adding a scientific/mathmatical application was just sooo cool. And the crowd was a wonderful mix of crafters and mathmaticians all sitting there facinated. And I remember some conversations after the show, crocheters showing mathmaticans how to crochet, and mathmaticians sharing the possible applications for this kind of science. (There was a woman sitting next to me, effortlessly knitting a pair of fair isle socks. I thought, one day I'll have to try that.)
(And while at the Lacis Retreat this year, Patty showed us her tatted hyperbolic plane.)

Here is the recent TED talks video.
