This is the first time I've used a pencast. Some things worked (technically speaking), some things didn't. And, I don't know if it was as conceptually clear as it could be... but, I wanted to try this and see what you thought.
You can download a PDF version of this pencast (requires Acrobat Reader 10 or higher).
There are three pages, each one 6-7 minutes long. Give them a listen, and your feedback is much appreciated. Use the comments below. Constructive comments that lead to improvements in future pencasts are most appreciated.
