I'm currently reading Surface Detail by Iain M. Banks. It's the latest in a series of his that is based around a super advanced, space-faring civilisation called The Culture, a decadent people who many millennia ago developed giant sentient spacecraft called Minds. The Minds' are unfathomably intelligent and exist and think in more dimensions than the usual three. They are also in some cases huge, often housing billions upon billions of people in a space that could easily be mistaken for a natural environment as opposed to the interior of a man made ship (technically the ships are made by other ships rather than men, but I digress). It is a tiny segment of one of these craft that I have chosen as my environment.
Oh, look out for a traditional style flying saucer, a surf board attached to a kite, a diving bell, Da Vinci's helicopter, a beat up old car and a giant flying bottle of Irn Bru.
