Michael did some interesting genealogy diagrams recently - showing how half each of Elf and I became half of he and Marcus. It was beautiful, although it might not exactly reflect the latest science.
In any case - Michael has now been repurposed this diagram to be a kind of music notation. Like so many creative things he thinks up, this has been co-opted into his parallel world of "Noogets" - this is how Nooget music is written down. Apparently all Nooget music "starts with a quadruple note [chord] and finishes with a unaple note".
