Bricolage

Bricolage is a term used in several disciplines, among them the visual arts, to refer to the construction or creation of a work from a diverse range of things that happen to be available, or a work created by such a process. The term is borrowed from the French word bricolage, from the verb bricoler, the core meaning in French being, "fiddle, tinker" and, by extension, "to make creative and resourceful use of whatever materials are at hand (regardless of their original purpose)". In contemporary French the word is the equivalent of the English do it yourself, and is seen on large shed retail outlets throughout France. A person who engages in bricolage is a bricoleur.
