Early Pixar: Luxo Jr.
From Wikipedia:
Luxo Jr. is the first film produced in 1986 by Pixar Animation Studios, following its establishment as an independent film studio. It is a computer-animated short film (two and a half minutes, including credits), demonstrating the kind of things the newly-established company was capable of producing.It is the source of the small hopping desk lamp included in Pixar’s corporate logo. In a subsequent re-release after Pixar became popular, a pretext was added to the film reading, “In 1986, Pixar produced its first film. This is why we have a hopping lamp in our logo.”

It was Pixar’s first animation after Ed Catmull and John Lasseter left ILM’s computer division and was also John Lasseter’s directorial debut. Lasseter’s aim was to finish the short film for SIGGRAPH, an annual computer technology exhibition attended by thousands of industry professionals. Catmull and Lasseter worked around the clock, and Lasseter even took a sleeping bag into work and slept under his desk[1], ready to work early the next morning. The commitment paid off, and against all odds it was finished for SIGGRAPH.
“Luxo Jr. sent shock waves through the entire industry – to all corners of computer and traditional animation. At that time, most traditional artists were afraid of the computer. They did not realize that the computer was merely a different tool in the artist’s kit but instead perceived it as a type of automation that might endanger their jobs. Luckily, this attitude changed dramatically in the early ’80s with the use of personal computers in the home. The release of our ‘Luxo Jr.,’ … reinforced this opinion turnaround within the professional community.” Ed Catmull, Computer Animation: A Whole New World, 1998.
