A graphic identity that users select to represent themselves in a chat, instant messaging (IM) or multiplayer gaming session. An avatar is generally a caricature, rather than a realistic photo, and can be anything from a simple cartoon to a bizarre fantasy figure. However, images of real objects are also used. The term is a Sanskrit word that means the incarnation of a god on earth, and this usage of the term came from the gaming and 3D chat worlds. See VRML
