So, first off... This is a very old head model that I finally decided to finish. I started making it with a lipsync idea in my mind. I wanted to animate a quote that I really like.
[btw, ignore that video - it doesn't matter.]
I was also looking for a new way to rig a face. Blendshapes seemed like something that I've played with enough, joint setups seemed somewhat too hardcore. I was even looking for something that would rig the face automatically. But I found something more interesting.
It is Kickstand's Stretchmesh. [The video's about Kickstand's Facelift, which is based on Stretchmesh, so you'll get the idea.]
Here's the official website.
They have a very basic explanation of how to use Stretchmesh so I had to figure out the rest. It was fun and I understood the benefits and drawbacks of this technique.
It is very intuitive and easily tweakable but in some cases other means are more appropriate to achieve the desired result.
So here's a little test video.
