16th century German soldiery sure understood how to strike terror into their enemies' hearts: the rooster-headed armored visor (ca 1530) must have been a sight to behold. Now on display at the Met in NYC (Bashford Dean Memorial Collection, Bequest of Bashford Dean, 1928)
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.
