In what I believe to be a first, an editorial cartoonist who also creates Web animations from his work has won the coveted Pulitzer Prize for editorial cartooning. The Pulitzer entry from Walt Handelsman of Newsday includes his Web animations. See the work of this year’s Pulitzer winners.
Also, make sure to check out the work of the Pulitzer editorial cartoon finalists. The Houston Chronicle‘s Nick Anderson actually turns some of his animated cartoons into games. Mike Thompson at the Detroit Free Press also does animation. They also submitted animations in their entries.
