  Wheeler's {\it observer-participancy} and the related {\it it from bit} credo
refer to quantum non-locality and contextuality. The mystery of these concepts
slightly starts unveiling if one encodes the (in)compatibilities between qubit
observables in the relevant finite geometries. The main objective of this
treatise is to outline another conceptual step forward by employing
Grothendieck's {\it dessins d'enfants} to reveal the topological and
(non)algebraic machinery underlying the measurement acts and their information
content.
