Assemblage is an artistic process in which a three-dimensional artistic composition is made from putting together found objects.

Found art—more commonly found object or readymade—describes art created from the undisguised, but often modified, use of objects that are not normally considered art, often because they already have a non-art function.

Bricolage is a term used in several disciplines, among them the visual arts and literature, to refer to the construction or creation of a work from a diverse range of things which 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, "make creative and resourceful use of whatever materials are at hand (regardless of their original purpose)."  A person who engages in bricolage is a bricoleur.

Ephemera are written and printed materials not intended to be retained or preserved. The word derives from Greek, meaning things lasting no more than a day. Some examples of ephemera are printed advertisements, menus, cataloges, greeting cards, letters, pamphlets, postcards, posters, airsickness bags, stock certificates, bookmarks and concert tickets.
