Since you're interested in art and OuLiPo you might enjoy The Lighter Side of Perl Culture (Part III): Obfu - which notes that the Paris Perl Mongueurs have a long-standing interest in both OuLiPo and Perl obfu. Both BooK and stefp helped me a lot with that article and I was very grateful for their assistance. BooK was the one who pointed out the similarities between Perl obfu and OuLiPo as an art form, both being based on constraints.
