Old women chalk up kind words on the sidewalks. Actions are what make it a vibrant village, arched dome overhead. Neighborhoods can also appear as they do in Lyubov Popova’s 1913 painting Composition with Figures. I’m reminded of old books like Eric S. Raymond’s The Cathedral and the Bazaar. Distributed control systems — when what I really want is a garden. I can’t hear the title of John Sinclair’s essay, “Rock and Roll is a Weapon of Cultural Revolution,” without picturing the Orpheus character in Samuel R. Delany’s The Einstein Intersection, who makes music with his blade. In the one, instruments are re-imagined as weapons; in the other, the weapon and the instrument are one.
