-       They had the idea for the pixar lamp by on day one of the writers was sitting at his table and a lamp was next to him he got an idea so he started to draw some ideas the same week his colleague has a child so he had the idea of making on of the lamps the father then the other lamp the child. He made a little 15 minute show about it, it got so popular that it was made the new face for pixar.

 -       They showed 25 pixar movies because pixar has been up and running for 25 years.

-       There are a lot of famous faces that play the characters in the pixar movies.  

-   The animated characters pixar make are mainly based on the people who play their voices.

- Computer animation or CGI animation is the process used for generating animated images by using computer graphics
Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, and for faster real-time. Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film.
Computer animation is essentially a digital successor to the stop motion techniques used in traditional animation with 3D models and frame-by-frame animation of 2D illustrations. 
It can allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props.
To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by a new image that is similar to it, but advanced slightly in time (usually at a rate of 24 or 30 frames/second). This technique is identical to how the illusion of movement is achieved with television and motion pictures.
For 3D animations, objects are built on the computer monitor (modeled) and 3D figures are rigged with a virtual skeleton. For 2D figure animations, separate objects and separate layers are used, with or without a virtual skeleton. Then the limbs, eyes, mouth, clothes of the figure are moved by the animator on key frames. The differences in appearance between key frames are automatically calculated by the computer in a process known as morphing. Finally, the animation is rendered.
For 3D animations, all frames must be rendered after modeling is complete. For 2D animations, the rendering process is the key frame process, while morphing frames are rendered as needed. For pre-recorded presentations, the rendered frames are transferred to a different format or medium such as film or digital video. The frames may also be rendered in real time.
