Program Composition: Slides ready 

I say ready, but I am going in the wrong direction with time.  Something is
going to have to give, either with the next section or these existing
ones.  I want time for interactive demonstrations.

You don't need to be a programmer to know how to do this;
you just need to be familiar with the tools and know what's possible,
which comes with a little bit of practice.
It can certainly be daunting at first.
But I hope that by walking you through these examples and showing you how to
construct them step-by-step,
it helps to demystify them and show that there is no wizardry involved.
This is certainly an efficient means of communicating with the machine.
