In designing a spoon that has eyes we had to come up with an eyelid system as well. This is what I came up with, just a half sphere eyelid that when in different positions will indicate different emotions.
(Please ignore the fork sticking halfway in the frame)
This is the normal position
This is the nervous position.
This is the sleepy position.
And this is sneaky.
This was a very early version of Jaques, in the more recent version the body, mustache and eyebrows changed, but the eyelids remained the same.
