Schedule composition diagram

Here's what I'm doing this week: the 28th annual Mathematical Foundations of Programming Semantics conference.  I am presenting a paper there, "A graphical foundation for schedules", joint work with my PhD supervisors Guy McCusker and John Power.  There's a preliminary version of the paper which will eventually appear in ENTCS.  The talk had slides, though they contained unnecessary illustrative animations which are not there on the pdf.
