Ben Schott of Schott’s Vocab has a feature on BBC Radio 4 about the Oulipo:
Founded in France in the 1960s, Oulipo – Ouvroir de Littérature Potentielle (“The Workshop of Potential Literature”) – is a literary movement dedicated to exploring new possibilities in writing through the use of playful (but strict) rules, for example: avoiding the use of a vowel, or replacing every noun with the seventh noun following it in a dictionary. These rules are designed both to test the mettle of the writers and to demonstrate that creativity can be inspired by constraint.
