Gerasimos,
There was another thread discussion about agents here: http://www.courselab.com/db/cle/B91274E976A1C5F8C32576B20005F983/main_id/DEB1AE8A7B1B3576C3256FCF0055974C/forum.html
I posted some alternatives for creating "animation-like" actions. Once you get a feel for the Actions in CourseLab, you may find they provide a lot of flexibility to accomplish what you need (even using images of yourself [:)] )
