Oulipo

Oulipo (, short for ; roughly translated as "workshop of potential literature", stylized ''OuLiPo'') is a loose gathering of (mainly) French-speaking writers and mathematicians who seek 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 and Jean Lescure, and poet/mathematician Jacques Roubaud.

The group defines the term ''littérature potentielle'' as (rough translation): "the seeking of new structures and patterns which may be used by writers in any way they enjoy". Queneau described Oulipians as "rats who construct the labyrinth from which they plan to escape."

Constraints are used as a means of triggering ideas and inspiration, most notably Perec's "story-making machine", which he used in the construction of ''Life: A User's Manual''. As well as established techniques, such as lipograms (Perec's novel ''A Void'') and palindromes, the group devises new methods, often based on mathematical problems, such as the knight's tour of the chess-board and permutations.
