Juan Cabana manufactures and sells fake mummified mermaids based on the Feejee hoax-mummies of yore. His site has a gallery of his macabre creations as well as a nice pictorial selection of antiquarian mermaids. Link (Thanks, Rollertrain!)
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.
