Icon design is the process of designing a graphic symbol that represents some real, fantasy or abstract motive, entity or action. In the context of software applications, an icon often represents a program, a function, data or a collection of data on a computer system.

Icon designs can be simple, with flat two-dimensional drawing or a black silhouette, or complex, presenting a combination of graphic design elements such as one or more linear and radial color gradients, projected shadows, contour shades, and three-dimensional perspective effects.

The term mascot – defined as a term for any person, animal, or object thought to bring luck – colloquially (informally) includes anything used to represent a group with a common public identity, such as a school, professional sports team, society, military unit, or brand name. Mascots are also used as fictional, representative spokespeople for consumer products, such as the rabbit used in advertising and marketing for the General Mills brand of breakfast cereal, Trix.
