Musical rendition of Demand and Supply

This is a great way to learn - singing about the concepts instead of memorising them.
Enjoy this one on the law of demand and supply.

The Jing On screen Video Capture

Did not really have the time to explore Jing during the Web 2.0 course, but hey, was enlighted with tips and tricks at one recent Mel Bytes session. This is what I tried to do - using Jing to explain how to do sound recording in MS Powerpoint 2007. This sound recording feature wasn't available in the 2003 version, and we had to download something (can't remember what!) from Mel in order to add a voice-over to the slides.

I have uploaded the file on to the Screencast website

Not sure why, but the video appears skewed to one side, and ahem, you can't see quite so well! Got to figure that out..
