Maybe the solution to the Neanderthalness is to just stay within the lines
of the image I'm using as a rotoscope--you can see the box in the anim.

 IIRC I had moved the frontal face flesh that far out so teeth would not
break the surface as the jaw opened.

LIPS??   I've figured out that Veggie Tales have lips (& mouth) which are a
mere bitmap pasted on the front.  The thought of making a lip on a blob face
that would lend itself to lip-sync voice shapes  just blows my mind.

It just had twelve phonemes (sp?).  I loaded the sound clip into MainActor
and played the track against an animation of  frame numbers.  After a half
dozen tries I had a frame number for each phoneme.  The mouth is just two
half-cylinders that cut into the face.  On a sheet of paper I figured out
the scaling factors for top & bottom cylinder as a function of frame number.
Then I made a simple linear_spline in pov that incorporated the cylinder
scalars into the x,y,z of a vector.

I don't think I"m too far from my ultimate goal:  a system where I simply
type into pov code:
   "p,o,v,r,o,x,b,a,b,e"
and
    "0,0.15,0.18,0.22,0.25, ..."
