The hands-down, undisputed, leader in digital animation is a company called Pixar in the United States. They are the people behind Toy Story (1995), A Bug's Life(1998), Toy Story 2, (1999) Monsters Inc., Ratatouille, and the latest movie UP. Originally, the studio was the computer graphics division of George Lucas's Lucasfilm before it was purchased by Steve Jobs in 1986.Even though Pixar's movies are generally 90 minutes, they take a long time to produce. Monster Inc. took five years to complete. Each movie produced by Pixar gets better, because the technology gets better. In Monsters Inc., for example, each of Sulley's 3.2 million hairs is individually animated. The hairs are computer designed as though they were springs with balls at the end. Five hundred key hairs are placed throughout Sulley's coat and a special computer program was created to make these hairs coordinate the movements of all the other hairs around them. The ultimate effect is a stunningly natural coat of hair.
