Avi sez, "Warren Seely tore apart his first tractor engine when he was six. When he was about 12, he started making farm equipment out of LEGOs. Warren's LEGO equipment works just like the real thing -- only smaller." (Thanks, Avi!)
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.
