It seems that email might not be the best medium of communication for 
this.  I am taking a page out of Knuth's handbook with something akin to 
literate programming.  Lacking a suitable TeX environment that works 
with LilyPond, I chose to do everything in a monolithic LY file.

May you find attached a compiled PDF with its LY source file.  I cannot 
promise the LY is the *most* readable, but I have tried to keep things 
as organized as possible.  Likewise, I have done a few passes of 
proof-reading over the document, but at this point I am unlikely to spot 
any typos that remain.  And rather than delay this further, I am sending 
out what I have, for better or worse.

Due to the nature of this presentation, there are parts of the LY file 
that are not directly relevant to the subject--including a number of 
helper functions for overlaying graphics on grobs, as well as a kludgy 
solution for including the text of a code snippet in the final document 
while also executing it.  Between just reading the PDF by itself and 
then along side the LY source, I hope it will not be too difficult to 
sort the wheat from the chaff.
