This amazing Stonehenge pocket-watch lets you "tell time like a Druid" by aligning the miniature circle of stones using a built-in compass and then looking at the shadows. As a bonus, it also predicts the winter and summer solstices. I love wildly impractical digital LED watch, but this analog watch takes first prize.

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.
