Non Intentional Design defies all standards, is subversivley and beautiful and part of all cultures. The book shows, how people can modify very banal things due to creative use. NID deals with norms which are "abnormally" transformed - every day, everywhere, by everyone. It is about the use and the exploitation of objects already designed. Amazing, funny and inspiring things arise, and a totally new point of view on well known workaday things evolves.
