OULIPO
Short for French: Ouvroir de littérature potentielle
Roughly translated: "workshop of potential literature" is a loose gathering of (mainly) French-speaking writers and mathematicians who seek to create works using constrained writing techniques.
The group defines the term littérature potentielle as: "The seeking of new structures and patterns which may be used by writers in any way they enjoy."
