A designer is a person who designs. More formally, a designer is an agent that "specifies the structural properties of a design object". In practice, anyone who creates tangible or intangible objects, such as consumer products, processes, laws, games and graphics, is referred to as a designer. Classically, the main areas of design were only painting, sculpture and architecture, which were understood as the major arts. The design of clothing, furniture and other common artifacts were left mostly to tradition or artisans specializing in hand making them.
