Pixar Animation

A animation from my childhood here from back in the day watching Disney films. The lamps movement is very well animated and the light coming from it reacts natuarally wherever it is facing. The bouncing effect on the I is extremely realistic and would like to experiment with such techniques myself.
Dispite the only using a gradient on the background you get a scene on a 3D space. Also a slight showdow at the bottom of the letters also help on add to the 3D effect.
