Knob Creek Metal Arts makes clever sight-gag book-ends and sells them on Etsy in a variety of finishes. The seller adds, "Keep in mind that I can customize anything seen here and am always open to creating custom items just for you."
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.
