bailenson suggested a texture solution.
I made the below arbitrary example (edited .jpg file attached) after following this thread:
<http://www.worldviz.com/forum/showthread.php?t=776&highlight=texture+avatar>

I see now how different textures can be put on the avatars to look like the eyes are moving (if the .jpg on the head has eyes that are looking left/right/etc. from edits using image software like Paint/Photoshop/etc.).

If anyone has answers to may first post above, I welcome them.

Thanks,
Karla
