When things in 3D computer graphics move, they always perform best when they have a "track" to follow, a point layout already pointed along their route, along and across. In pursuit of what we know about the movements, we're going to build the eyeballs first, to have a reference to use when constructing our lids; then we're going to build the lids/sockets out of a mostly circular layout, to allow the squinting and blinking; ...
