Have discovered a useful site mentioned by a friend. Had got sidetracked with other things but finally visited it today while looking for some useful images for 'Exploring Genre 'War'.
It is very easy to use and has a wide range of visualisation options that students would enjoy playing around with it.
While many visit this blog, I still have the same 6 members I started with nearly a year ago and as yet, almost no members on my HSC ning. Apparently they are going to begin charging to host nings in January and so it will die a natural death. If you teach HSC English, I have put up some resources for a few of the courses now running. Have a look and use any resources of use before it all folds in a few months time.
Animoto is another software that could be useful although it costs money to get more than the free 30 second version I coddled together below.
