Kazushi Kobayashi's Chubu 01 is a robot from an alternate 1957 where robots are the primary mode of transportation. Build-it-yourself model kits are for sale in Harajuku's TOKYO CULTUART gallery at 28.000 Yen a pop ($350 or so).
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.
