Hi,
I am a student from the university of braunschweig, germany and I am going to deliver a small lecture on animation systems in about a week. One of the softwares i have to cover is Houdini but I never worked with it before. Now I need something like an overview and a short description of Houdini's special features for animation because it seemes to be impossible to find out everything for myself in that short time.
Points of interest are such things like cloth animation, muscles, fluids, special features for particles and so on. But feel free to point out anything you think is worthwhile mentioning.

thanks in advance
