UHHH, I don't think my kids would sit still if I start poking them in the face
with an electric drill. I won't even contemplate what my wife would do
to me, but I'm sure it would require surgery, at least!

Obviously, to digitize a face, you need to do it with light, or make a cast
of the face. That would work, maybe I should do the cast now, and then
figure out digitizing later.
