Be, I have nothing helpful to you. I see the eps as individual character lines, tangles, collisions, disengagements, etc., though the more diagrammatic view you detail above is just as valid, although a back step more abstract. I'm watching the people, not the patterns. Not meta enough to take you farther than you've already gone. I find your analysis most illuminating but cannot offer you a link to similar paridigms--as with your analyses of body language or the use of color.

I enjoyed reading this and regret I cannot usefully add to it.
