Hmmm. I'm not sure I follow. Isn't this the cannon with each part
starting at a different place in the theme? Isn't this the one where I
pointed out the "diagonal of 1/1's" in the graphic representation? Or was
that a hasty analogy?

Well, it might not fit well into the genre called "algo-comp", but I sort
of use the words process and algorithm interchangably here.
