I've just done the first ... of what I plan to be a ongoing series of screencasts ... of mini-tours around the Shambles Website ... this first one is about the "Mobile Phones in Education" section.
I'm using a web-based screencasting application to make these ... http://screenr.com/user/shamblesguru
I need to work a little more on the audio volume and the best dimensions for these screencasts ... they are really quick and easy to do, a brilliant application for students.
