Plussing - The art of adding little touches to a project, whether a film or a park attraction, to make it better. Walt Disney especially had a talent for plussing everything he worked on. He tried to constantly strive for top quality, to do things better than anyone else was doing them. One example of Walt's knack for plussing was the addition of fireworks to the roof-top scene in "Mary Poppins."
