Visual Tutor Personal Description:

Visual Tutor is, at its simplest, a tool that lets you create, quickly and easily, a visual, audio, and interactive presentation for the purpose of teaching some skill, whether it be a computer application, or some other skill.

Visual Tutor's goal is to make the creation of computer based training programs easy to do without any hassle. Just take some screenshots, add explanations, perhaps some quizes, and you've got a ready to distribute tutorial.
