1. A method for creating a computer-implemented avatar, comprising: capturing a plurality of detectable attributes of a user; comparing said plurality of detectable attributes with a normalized model of attributes, wherein the normalized model of attributes characterize normal representative attribute values for a particular sample across a plurality of users; and customizing at least one avatar by applying at least one differential attribute representing the difference between the plurality of detectable attributes and the normalized model of attributes, 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.
