Pink Tentacle describes the practice of growing giant rice-paddy illustrations "by growing a little purple and yellow-leafed kodaimai rice along with their local green-leafed tsugaru-roman variety." There's a fantastic gallery of these illustrations, ranging from "36 Views of Mount Fuji" to various demons, gods and traditional illustrations, as well as the Mona Lisa. Link (Thanks, Karen!)
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.
