Dawnoh's 2009 Zippo Tricks video has garnered over 2,000,000 views. She's quite a virtuoso and I love her super-cool, like-a-boss affect -- but be sure and watch to the end for her blooper reel. Doing lighter tricks the the only thing I miss about being a smoker, though truth be told I'd already had all my Zippos stolen from me by the TSA by the time I quit.
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.
