David Pescovitz recommended this to me recently. Apparently this guy made tons of influence diagrams. He also was connected to lots of artists, musicians, and attention mongers – who I have now added to Freebase.
George Maciunas (November 8, 1931 – May 9, 1978) was a Lithuanian born, American artist who was a founding member of the Fluxus, an international community of artists, architects, composers, and designers. Maciunas is generally credited with having invented the name “Fluxus.”
His life-long interest in diagrams made him chart the political, cultural and social history as well as art history and the chronology of Fluxus.
