Polish leatherworker MK makes some very nice wrist-straps for pocket-watches and car-watches. He's not the only one making these, but I find them particularly handsome, and rather nice retro-modern take on the massive wristwatch phenomenon.
Wristbands for pocket watches. (Thanks, Nic!)
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.
