The Pixar production logo is a sequence that appears at the beginning and end of most Pixar productions movies, and features a playful desk lamp. The 1986 short film Luxo, Jr. is the source of the small hopping desk lamp included in Pixar's logo. In To Infinity and Beyond!: The Story of Pixar Animation Studios, a book of Pixar's history up through January 2007, film critic Leonard Maltin said that he "like[s] the fact that Luxo still has significance to the people at Pixar", and remarked that it was something like Disney's Mickey Mouse.
