The dish and the spoon were mostly 2D puppets for Goodnight Moon. Part of the challenge was that they each needed to be easily operated with one hand, because the same actress was operating both puppets at the same time (in addition to playing a third character herself, quite a feat). To start I created a base shape for each puppet on a piece of 1/4" ply.
parrot and the curious child that I built previously. The mechanism requires a plate on a pivot to function as the jaw, a string to pull the jaw down on the pivot, and a spring to pull it back up.
