The "Ask Me About My Facehugger" tee is a pretty good riff on the flip-up t-shirt design. Great choice for anyone who's virtuously spent the Xmas gorging season grinding away in the gym, honing their abs while the rest of us ate our way to plum-pudding/brandy sauce comas.
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.
