Wink - creating animated tutorials

Wink is a free tool for creating animated tutorials and software demonstrations. Wink lets you capture screen shots of your software, add instructional text callouts and navigational buttons, and export your tutorials to Flash, HTML, PDF, or stand-alone executable files. By using templates you can create a standard look for all your Wink tutorials.

A few quirks and bugs in the 1.0 version. (Version 1.5 is expected soon.)
