Disobedient Objects' is about out-designing authority. It explores the material culture of radical change and protest - from objects familiar to many, such as banners or posters, to the more militant, cunning or technologically cutting-edge, including lock-ons, book-blocs and activist robots. Where previous social movement histories have focused on large-scale events, strategies or biographies, this book - and the exhibition it accompanies - shows how objects themselves can be revolutionary.
