This paper extends the scope of algebraic computation based on a non standard × to the more basic case of a non standard +, where standard means associative and commutative. Two physically meaningful examples of a non standard + are provided by the observation of motion in Special Relativity, from either outside (3D) or inside (2D or more), We revisit the "gyro"-theory of Ungar to present the multifaceted information processing which is created by a metric cloth W, a relating computational construct framed in a normed vector space V, and based on a non standard addition denoted ⊕ whose commutativity and associativity are ruled (woven) by a relator, that is a map which assigns to each pair of admissible vectors in V an automorphism in Aut(W). Special attention is given to the case where the relator is directional.
