Etsy's GreenTreeJewelry makes these whimsical, rube goldbergian light-switch covers that let you toggle the switch by means of a delightfully superfluous mechanism: "This light switch cover is completely functional. Levered handle toggles back and forth, turning on and off light switch."
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.
