Infra-mince@Everything2.com
Infra-mince, Duchamp declared, cannot be defined, but can only be described by examples, such as the difference in displaced volume between a clean shirt and the same shirt worn once, or the taste of one’s mouth lingering in exhaled smoke.
Infra-mince was a new way to think about physical and temporal dimensions (decades before Mandelbrot discovered fractals). Holes in some of Duchamp’s artwork link the 2nd to the 3rd dimension. Sometimes he shot the holes out with bullets, echoing infra-mince again in the delay between the sounds of the shot and the impact.
Add this to the isovism concept and you basically describe a social network.
