The fabulous Singularity & Co bookstore (where they find out-of-print sf classics, clear the rights to them, and bring them back as CC-licensed books) is finally selling its beautiful "Boom Tee" online, designed by Wesley Allsbrook. I saw this at NY Comic Con and wanted desperately to blog it then -- glad to see it online at last!
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.
