Fifth speaker is talking about "Computer Vision Syndrome" and quoting #AnneFriedberg. Now she's talking about MS Windows and maybe how the overlapping nature of windows on a desktop contrasts with paintings like Alberti's Window and Magritte's window painting, and Friedberg's writing about windows. She quotes #JosephPieper and #TheInvisibleGorilla. Then moves on to "trees blindness" and tree walks. Then to teen use of#SocialMedia and discourses of #DigitalNarcissism.
