Back in my day, textbook sketches were usually just vulgar, talentless nothings, but these beautiful designs by artist Paula Swisher are quite the exception.
Using leaves of paper from old engineering and science manuals as her canvass, Swisher brings what she describes as a "contrived sense of order" to pages of numbers, figures, and graphs — creating what she calls "a visual metaphor for our attempts to make sense of our experiences."
Don't miss the rest of these amazing drawings on her website.
