"Mobile phones have replaced design in mediating our relation to the surrounding space," writes Italian artist and composer Riccardo Benassi (born 1982). "All the tools that surrounded us were dematerialized. To stay alive--and to survive the digital--objects have become invisible, and are often processed in their own narratives." Equal parts essay, diary and critical pamphlet, Techno Casa is the fifth publication in Errant Bodies' Doormats series.
