The original post is now organized by category, which makes things easier to find. I've also added a few links I've found in the past month, a few things suggested in a discussion on the knittyboard, and some comments on geeky books that I either own, or have looked at. I plan on infrequently updating that post, rather than starting new ones, for the convenience of those people who would like to bookmark the page (hit the "permalink" link before bookmarking). Most of my projects have a high geek factor: fibonacci sequence, DNA cables, and continental drift / plate tectonics. And if I had only known about the cat bed incorporating the moebius strip!
