Carl "Boutros77" BouMansour is a fine artist and modeller in the UK who makes elaborate diaoramas based on science fiction movies, especially Star Wars. These are lavishly documented in his Flickr sets. There's a lot to love here, but I recommend starting with the pictures of the Cantina on Tatooine. It's such an ambitious miniature set, and the attention to detail left me amazed and delighted.

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.
