How to compose a photo using the rule of thirds

I am exploring all of the different ways I can think of to make a podcast or vodcast. For this one the basis was a Powerpoint presentation I had made some time ago for my class on composing photos using the rule of thirds. To turn the Powerpoint into a podcast I saved it as a movie then dragged that movie into iMovie to add the voice track. I had found another open-source music website and couldn't get the music track I wanted to download so played it through the laptop speakers and recorded it with Audacity. The result doesn't have the same sound quality as a downloaded MP3 version but it is OK. I hope the topic of the Powerpoint is useful to you. 9MB 3 minutes 38 seconds
