This site lists lots and lots of fun geek knitting. I'm absolutely going to learn how to double knit so that I can make that tectonics scarf.
ETA: The other day Marie asked our new coworker if she wanted to join the needlework group. Said new coworker burst out laughing. "I'm not a domestic person," she said, among other things. This part struck me because I don't think knitting is really domestic, any more than woodcarving is. Nobody's household depends on knitting for clothing. It's just a hobby. Apparently shopping and manicures are more her thing. Different strokes (of the needles or polish brush, respectively, I guess).
