This sweet little egg-cup is 3D printed on demand through Shapeways, where it sells for $7.14. It was created by Shapeways user Gijs, who's got some other interesting designs on the site.
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.
