Escher is the popular example when thinking about art influenced or exmplifying the concept of recursion. In Gödel, Escher, Bach: an Eternal Golden Braid, Douglas R. Hofstadter makes some connections between the music of Bach, Escher's art and other areas of knowledge related with recursion and self-reference. I was wondering what other works of fiction in film or literature exemplify recursion in their structure. That is, not works about recursion, but works in which recursion plays some kind of role in their structure or meaning.
