With an interdisciplinary approach, the independent publishing platform HipoTesis was set up in 2009 with the objective of creating a place, a network for the exchange of ideas, proposals, and reflections, establishing connections and promoting dialogue among the participants. Under the title Fábrica de Bloques (block factory), the first printed issue (the publisher has two series of online magazines, one by numbers, the other by alphabetical order), gathers fifteen graphic reflections about the meaning of CAD ‘blocks’ today, three decades after their creation, proposing to update and adapt them to a more heterogeneous society and to new customs and lifestyles.
