The lamp animation reflection

The bigger lamp is obviously older because it was standing on the spot and shaking his head when watching the other lamp play with the ball. It is also due to the fact that it does not move around, thus showing a lack of youthful energy. The smaller lamp is obviously younger because it is very energetic, moving around the place restlessly. The wire which is linked to the small lamp is also timed to create a sort of wave like appearance to show movement of the lamp. Joints are needed to prevent the animation from having logical errors.
