The interpolation was linear, but it is planned to be enhanced with
different methods. As you mentioned, linear looks a little cut off, and I
sure don't want to look like an amateur in my first Short Movie! :-)

As for the lips looking too fixed: I've added that displacement-mapping,
moves the lips, regardless of the underlying spline, more in- or outwards,
in relation to the normal of the lips at that point. This should make some
cartoonish effects possible, but also enable that slight movement. Maybe
I'll add some other features for that as well, depends on which ideas I come
up with and how I can implement them on the underlying structure.
