I can't think of any code which I read and reread. For that matter, there are few books that I reread frequently. The closest is for a software library which I use only occasionally, where it takes a few non-intuitive lines to get things set up correctly. Someone developed an easier API for it, which is closer to the way I think about the problem. When I need to X, I consult that software to see how to implement it.
