The Inspirations 4 Your Life tumblr had a great suggestion for entertaining your kids: "Make a 'laser grid' by taping yarn to the walls and let your kids try to get though it.

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.
