Oulipo

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 which seeks to create works using constrained writing techniques. It was founded in 1960 by Raymond Queneau and François Le Lionnais. Other notable members have included novelists Georges Perec and Italo Calvino, poets Oskar Pastior, Jean Lescure and poet/mathematician Jacques Roubaud.
