Luxo Jr. is a 1986 American animated short film produced and released by Pixar. Written and directed by John Lasseter, the two-minute short film revolves around one larger and one smaller desk lamp. The larger lamp, named Luxo Sr., looks on while the smaller, "younger" Luxo Jr. plays exuberantly with a ball to the extent that it accidentally deflates. Luxo Jr. was Pixar's first animation after Ed Catmull and John Lasseter left the Lucasfilm Computer Division. The film is the source of Luxo Jr., the mascot of Pixar.
