This little screencasting app, ScreenJelly, seems very easy to use, though it has only a 3-minute recording time limit. You can record what you are doing on your computer screen with your own voice-over. The program is very self-evident, i.e., it takes only a few minutes to figure out how to use it (and there is a helpful how-to video both here and at Stannard's TTV site). I can see its immense usefulness for a teacher (or students) to create little help videos for new technology learners. Links or embedding are possible with such social Web tools as Twitter or Flickr, et al.
Thanks to Russell Stannard--found on his most useful site.
