1. A method for creating a computer-implemented avatar, comprising: receiving, by an avatar creator system, at least one differential attribute from a differential system, wherein the differential attribute represents the difference between a plurality of detectable attributes captured of a user and a normalized model of attributes, wherein the normalized model of attributes characterize normal representative attribute values for a particular attribute as sampled across a plurality of users; customizing an appearance of at least one avatar, by the avatar creator system, by adjusting at least one adjustable attribute of a base avatar definition by the at least one differential attribute, wherein the customized avatar reflects a selection of the plurality of detectable attributes of the user which are distinguishable from the normalized model of attributes as applied to the base avatar definition; and graphically distinguishing the customized portions of the appearance of the at least one avatar as applied to the base avatar definition by displaying an additional graphical attribute applied only to the customized portions of the at least one avatar reflecting the at least one differential attribute.
