A version of Moby-Dick where every word hyperlinks to every other instance of that word, front to back, in a cycle. So, the first word, "call," links to the last instance of "call" in the book. The next instance of "call" links to the next-to-last instance, etc.
@leftfield To be clear, I envisioned this working so that if you clicked on a link late in the book, it would send you back towards the earlier parts, too.
