Children's Book author/illustrator Chris Raschka has created an entire book around Monk's "Mysterioso," called Mysterious Thelonious. It's literally a visual interpretation of "Mysterioso," with a colored grid on the pages standing in for the notes, and the words jumping up and down from tier to tier in emulation of the tune. Should have come with a record, but anyone who buys it for their kid most likely already has the record. Take a look at it here: http://www.amazon.com/exec/obidos/tg/detai...=books&n=507846
It's funny, to me at least, because from the very first time I heard it, "Mysterioso" sounded to me like an ultra-hip children's TV show theme, with its odd yoking of the innocent and the sophisticated.
Raschka also has a kid's book based on Coltrane's "Giant Steps" and another called Charlie Parker Played Be Bop.
Only semi-related, but this thread reminded me of it.
