WINK is an excellent free and opensource screen capture program you can use to develop tutorials on software applications or your own website that can be placed easily on Joomla websites. All you need to do is insert some code in an article using the Sourcerer plugin after WINK has rendered the SWF and script files for you.
You can capture screenshots, add explanations boxes, buttons, titles etc and generate a highly effective tutorial for your users.

You can copy and paste the code below (in this case the files are in the directory wink):
