"Another way we might think about potential literature is via an analogy with potential and kinetic energy. If potential energy is stored in an object, then we might say that potential literature is embedded within a language. In the first case, the field of gravity would determine an object’s potential energy; in the case of literature, the field of memory would determine a work’s potentiality. Pushing the analogy further, we can compare the conversion of potential energy into kinetic energy to the conversion of potential literature into real texts. In physics, that conversion is expressed through motion, in literature it is expressed through two related ludic activities, both of them realized at the level of the letter: the crafts of writing and reading with volition."
The quote speaks primarily of Oulipo however I think it can be said of many forms of experimental writing. While I am happy that Ouilpo has so much interest, I am a bit envious due to be believing that there could be a lot more experimentation with "Substitution in Mathematical Poetry" as well. While both are forms of experimental writing the approach language very differently even though I see both being rooted in formal science.
