Okay, this is OuLiPo for anyone, not just for Li Po, and it can be found at the blog We Who are About to Die, five links to using OuLiPo restraints in your own writing.
A particularly fun one is an online N+7 generator. N+7 is a technique in which nouns in a text are replaced by the noun that occurs 7 noun-entries later in the dictionary than where the original noun can be found. But which dictionary to use? And what exactly counts as a noun? All these concerns are eliminated by using the N+7 generator, made by OuLiPo-ist Jean Lescure. Just type in, or cut and paste, your text and let the generator make all the calls for you.
