This 24 hours is about strengthening your imagination muscles. Pick a work of fiction to read that helps you think about the future. You could do this for yourself, or with others, such as a book group. Choose a book that isn't just a dystopia. It could be a utopia, such as Marge Piercy's 'Woman on the Edge of Time'. It could be a mix of good and bad, such as Bruce Sterling's 'Distraction'. And it doesn't have to be American - try Sarah Hall's splendid 'The Carhullan Army', which won the John Llewellyn Rhys prize - it's set in Cumbria.
