Soft Body Dynamics

I am trying to learn how soft body dynamics work in 3D apps, and I'm using Blender to do it. Blender is a free, open source animation program that can be downloaded from the web, and there are a bunch of Wikibooks out there for tutorials. I'm hoping to incorporate some of this into the next episode of BRINE, and so far, I have a convincing liquid going, although its still not quite right viscosity-wise. (The following video, I should mention, took almost 2 days to render on a hyperthreading Pentium 4 proc. Next time, I'm using the damn G5).
