four twitter icons drawn by hand

Greek , eikon, "image") is an image, picture, or representation; it is a sign or likeness that stands for an object by signifying or representing it, or by analogy, as in semiotics; in computers an icon is a symbol on the monitor used to signify a command; by extension, icon is also used, particularly in modern popular culture, in the general sense of symbol — i.e. a name, face, picture or even a person readily recognized as having some well-known significance or embodying certain qualities.
