Chrislea: great find!
ILoveSGPL: if you don't mind some self promotion (I run the website), check out the growing collection of Star Wars knitting/crochet projects I've pulled together (both free and $). http://starwarsknitting.com If you find anything I haven't yet included, let me know (as long as it's on-topic) and I'll add it.
Go nerd knitting!
Also, check out http://fuckyeahgeekknits.tumblr.com/ or the Knits for Nerds book (I haven't seen it yet) http://www.amazon.ca/Knits-Nerds-Projects-Science-Fiction/dp/1449407919
