Yakkay's bike-helmets look like hats -- just slip a cover on (they come in beanie, sunhat, peaked cap and a couple other varieties, and in many colors) and pedal your way to sartorial splendour. Yakkay (via A Whole Lotta Nothing)
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.
