Gestalt is a German term describing a design’s wholeness. When we look at a design and say, “This design works!” what we are describing is the overall Gestalt quality. How this is so is defined by this Gestalt term: A design’s unity is more than the simple addition of its parts. Very simply it means that each part of a design is affected by what surrounds it, and that we can affect the cumulative perception by manipulating the interaction of the individual parts.
