William Joyce is a seasoned illustrator, writer, director, producer, and designer who lives in Shreveport, Louisiana. Joyce has done a ton of work which you may have heard of, like Rolie Polie Olie, Meet the Robinsons, Robots, George Shrinks, Dinosaur Bob, and the upcoming Dreamworks film, The Guardians of Childhood. I found this little video series on a great website promoting illustrators and writers called Reading Rockets. Joyce has a great outlook and puts out good karma, and I think he sees great returns because of his fun attitude and open way of imparting knowledge and technique.
