What are some good applications for creating lecture-like videos?

I want to make videos like the ones in this YouTube playlist.

Where I can write stuff and talk about stuff at the same time.

My first instinct was to shop around for a pen-tablet I can use to do the writing, but then I realized I didn't know what kind of software I would need to make "pen-tablet videos" and whether such software would be compatible with the specific pen-tablet I would buy.

So those of you who know how this could be done on Ubuntu, what are the (software and compatible hardware) tools I would need to make videos like that?
