" Du Corps à l'Avatar ": the two prepositions could be pointing towards a same direction, a vector line, a narrative sequence. An evolutionary ride. But the intention is rather to define the spatial fringes, the margins within which a complex territory is developping. The two first issues of Anomalie intend to explore some segments of this territory. This theme is, doubtless, a topical one : how digital technologies change the body (forms, behaviours, perceptions, status). The debate is animated : some point out the part of materiality due to simulation or virtuality, others claim that, thanks to interactivity and multimodal interfaces, the body is assuming more crucial a role than it ever did.
