You'd probably like Wooly Thoughts (I think it's http://www.woolythoughts.com). It's geek knitting, quilting, etc. Also in various places online you'll find a DNA scarf, a charming bag/container based on the mathematics of prime numbers, a 3D knit model of DNA suitable for children and, of course, myriad Fibonacci patterns. ^_^

I <3 Wooly Thoughts. Also, I still need to crochet some hyperbolic planes.

I'm a dork. They spell it "Woolly," so it's http://www.woollythoughts.com not the link I wrote out. Anyway, check them out if you're so inclined.
