In 2002 Nintendo released Legend of Zelda: The Wind Waker for GameCube. One of the great things about the title (which was not well received when it first came out but is now rated highly in the Zelda pantheon) it its pioneering use of cel shading - a stylistic technique to add shading to 3D graphics to make them look less realistic (in a bad way) and more cartoony (in a good way).
