10 why the READABILIT Y OF SHAPES AND FORM is key
From the overall form to the least visible prop, every shape has to be readable. Even in a busy setup (see left), the effectiveness of information is not dependent on the details, but the readability of shapes. Even if those shapes were stripped of details to the point of silhouette, they will still be easily identifiable.
World War II pilots were trained to identify specific enemy ships at sea by reading their silhouettes. So I would say your designs must be exaggerated and simplified, with clear silhouettes working harmoniously.
