I gave a relatively technical tutorial on using Brian that might be of interest more generally. The tutorial was done via Skype so I could record what I was saying and insert that into the Powerpoint slides. You can download both versions below:

Powerpoint slides without audio (1.5MB)
Powerpoint slides with audio (15MB)

Unfortunately, I can’t find a good way to convert this into a video file or I would upload that / put it on YouTube - let me know if you have a good, free way of doing it. (None of the programs I found online could correctly handle the transitions and the audio files correctly.)
