This page from the TV Tropes and Idioms Wiki, on James Joyce’s Finnegan’s Wake, written entirely in Wakese.*
It’s brilliant, not only because it’s so fiendishly hard to write in Wakese at any great length, but because there’s absolutely no reason to do so, especially on a wiki ostensibly dedicated to cataloging tropes found in popular entertainment. It’s an obvious labor of love by a truefan who did it just for their own pleasure in doing something creative in honor of a work of art they clearly love. Which makes it all the more wonderful.
*Joycean prose made up entirely of literary and mythic allusion and portmanteau of English, Latin, Gaelic and French words.
