Thinkgeek's Star Trek TOS panties are steeped in the romance of a bygone era of space-exploration (there's also matching boxers). The mix-n-match possibilities are endless: "doomed redshirt and sympathetic medical officer"; "arrogant captain and standoffish (but secretly intrigued) Vulcan science-officer) -- I could go on.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
