Luxo, Jr. is Pixar's mascot and the star of the 1986 short film Luxo, Jr. He is a small, light gray desk lamp (although he has sometimes looked more of a white than light gray lamp) who loves to play with bouncy balls. After having the same light bulb for over 20 years, WALL-E had to replace it for him when it went out, which can be seen in the trailer for WALL-E, replacing the standard bulb with a compact florescent. Luxo, Jr. has been seen in every Pixar feature film and short film since Toy Story, during the film's introduction and at the end of the credits as the I of the Pixar logo.
Luxo, Jr.'s most recent (albeit temporary) upgrade was that of a laser for the teaser, regular trailers, and ending of Cars 2.

The Luxo, Jr. can be seen twice on the credits of Cars 2: the first over looking the Pixar Studios building on a map, and the second in an advertisement for "Air Luxo".
Luxo, Jr. appears in four segments: "Light and Heavy", "Up and Down", "Front and Back", and "Surprise", which aired on Sesame Street.
Luxo, Jr. also appears in the Disney Infinity games as a non-playable toy box decoration.
The inspiration for the design and size of Luxo, Jr. came from Spencer Porter, son of Tom Porter. Tom had brought his son to work one day and John Lasseter was inspired by how much larger Spencer's head was compared to the rest of his body, plus the size of his eyes compared to the rest of his head.
