Wink is free presentation and tutorial software which lets you record and annotate onscreen computer activity.
So if you want to demonstrate to a client how your site's bookmarklet works, or create a presentation to train summer interns how to use company software, start Wink screen recording, and perform those tasks on your computer. Then, within Wink, you can edit the captured frames and add annotated bubbles pointing to parts of the screen explaining what's happening. Save as a Flash .swf file for viewing within a web browser or as a standalone .exe file. Sorry screencasters, Wink does not record audio. Wink is free, Windows and Linux only.
