Before the "Nintendo wars" of the early 21st century, there were these toys, which invited young children to practice accurately releasing atom bombs. I'm not sure that the skills you learned with this gadget would translate into real A-bombing practice, though, which probably disappointed some youngsters.
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.
