From Carolyne Zinko's SF Gate story and slideshow from San Francisco's Folsom Street Fair (a kink/fetish event), this fantastic mask on an unidentified "reveler." I want to wear something like this on an everyday basis.
50 shades of fetish at Folsom St. Fair (Thanks, Fipi Lele!)

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.
