Something that really opened my eyes to thinking about the design of everyday things was "Objectified" (2009), a documentary on industrial/product design.
Could you expand on why this film came to your mind in this context. I also saw objectified but felt it was, to put lightly, a fluff self-glorification by designers.
We are immersed in the various mediums present in our daily life and being aware of the medium itself and what limitations or potentialities are available from that medium will demystify these otherwise mundane ubiquitous things we encounter everywhere.
In the context of "The Medium is the Massage", I brought up (industrial) design because physical products are a major part of our daily lives and I never really gave much thought as to how a tooth brush or a Macbook was developed and built. Yeah Objectified had a fair amount of self-glorification of the designer egos, but before I saw the film I had no real concept of who was behind all the stuff that I use in my daily life.
