Etsy seller Rivkasmom has these gorgeous cufflinks made from old watch-movements on sale for $55 -- I saw a similar item at a posh London men's store on Jermyn Street last week for £400! Link (Thanks, Dani!)
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.
