A beautiful example of a Oulipian work. Starting from 10 sonnets, Raymond Queneau devised a simple tool to generate 10 to the 14 (1 followed by 14 zeros or,  in plain English, one hundred thousand billions) sonnets by exploiting simple combinatorics. Just to give an idea, if you had just to count them, one per second, it would take you more than 3 millions years to complete the task. Check the video here and create your own favorite here (in French) or here (In English).
