Hyperbolic Crochet!

Interrupting midweek because this site http://theiff.org/lectures/13.html was mentioned on a crochet group and it's FANTASTIC! So now I combine crochet, physics and art. At long last. Haha! Look through the galleries, there's great images there and you can see the progression from a simple curved space to more complex structures - and of course tips on how often you need to increase to knit/crochet them.

Here's my very first one made this morning. I tied it to a little kilt pin so I could wear it for the day.
