British artist Su Blackwell hit on an unusual way to bring storybooks to life – by fashioning their pages into origami-like sculptures. Her intricately worked scenes are 3D illustrations of the stories they are made of. The artist says they are 'often pervaded by a sense of loneliness, since the stories on which they are based are rather sad'.

German-born photographer Wolfgang Tillmans has picked up the German Society for Photography's 2009 Culture prize for his portrayals of gay and club scenes in 1990s Germany.
