The A to Z of X – demonstrates evidence of ambiguity through the multiple manifestations of X: identity and anonymity, the universal and particular, love and death. A representative (alphabetic) scope of examples relating to X are visually collected, classified, evaluated and embodied in this artefact. Design mechanisms and structural tools are applied to encourage active engagement in the multi-layered ambiguities of X exploiting the form of a book: multiplicity page . This printed prototype is framed as a material object and concept of ambiguity.
