Over the years I have looked at several different e-Learning tools -- tools
  and systems that enable you to create multimedia presentations, narrated
  desktop movies, animated software tutorials, and online courseware. 
  Recently, I have evaluated  Turbo
  Demo, and I am happy to say it is one of
  the easiest tools in the e-Learning genre I have seen, yet it is very
  powerful.
  
  Like the majority of packages, you must start by taking
  snapshots of your application. With  Turbo
  Demo running in the background, you
  simply page through your application, and take snapshots by clicking your
  mouse. When you're all done, you can view your snapshots individually, or in a
  slide tray resembling Microsoft PowerPoint. Change the order, add comments,
  bubbles, animation, etc.
  
  When you are ready to make your demo file, you have many output options
  including Flash, Java, EXE or an uncompressed AVI video. When your demo
  is done compiling,  Turbo
  Demo  creates a web page allowing you to preview your work, and it
  includes explicit instructions and code for how to load the demo onto your web
  page. 
  This is where  Turbo
  Demo  really shines. It is the easiest demo development package I have
  ever seen, and the instructions are easy to follow making it a breeze to
  integrate your demos into your existing web pages. It's idiot-proof.
  The resulting compiled demo is also a fraction of the size you might
  expect. An average one minute demo compiles down to .1 MB! That is simply
  amazing, considering the quality of the output.
