The third thing: screenr-ing

I had watched YouTube and eHow videos that made use of this and wondered how they did it. How cool to actually know. This is a very rough first draft of a video, and if I had actually used it in class--or made a better one and used it in class--it would have saved me a whole lot of time explaining and re-explaining.

Anyway, here's the URL for the video I created: http://screenr.com/eF88 .
