Julijonas Urbonas, a PhD candidate at the Royal College of Art in London, designed this "Euthanasia Coaster" that will kill its riders with a series of brain-scrambling loops: "a hypothetic euthanasia machine in the form of a roller coaster, engineered to humanely -- with elegance and euphoria -- take the life of a human being. Riding the coaster's track, the rider is subjected to a series of intensive motion elements that induce various unique experiences: from euphoria to thrill, and from tunnel vision to loss of consciousness, and, eventually, death."
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.
