A full scale drawing of the idea for the piece turned up a problem with the eyeball set up used in the first prototype of the eye mechanism. The side of the space capsule it goes in has sloping sides. Having the eyeball's pivoting axis vertical turns out to not work in a sloping side capsule. For the eyeball to work properly IN the capsule, its pivoting axis has to have about the same slope as the side of the capsule. This axis tilt also gets the eye looking UP at you.
