1.    a manifestation of a deity or released soul in bodily form on earth...
2.     an incarnation, embodiment, or manifestation of a person or idea:

3.     an icon or figure representing a particular person in computer games,...

For some time now there have been web sites with talking cartoon characters. These are some kind of CAD cartoons. They might be called "Talking Avatars."

The Google link offers some examples.

To buy one of this program is, I assume, very pricey. I see there are a few free things out there. So, here is my question.
 Has anybody had any experience with using a free talking cartoon on your own web site recently? What did you use?
