When other rooms give us ideal moments of the history of design from the beginning of the 1900’s till nowadays. “Fluidity’s” theme cuts crosswise the whole history of design emerging punctually up to become paradigmatic of the determine period, so then to leave space for linear geometrically tendencies as, so-called, “Bauhaus” stile of the 20’s, Ulm’s approach of the 50’s and the 60’s or Minimal art  of the 90’s. Thus this room is a mix of various and heterogeneous artefacts, though having common formal consonance, represent very different design circumstances.
