"There was a period... when it looked as if graffiti would take over the world, when a movement which began as the expression of tropical peoples living in a monotonous iron-gray and dull brown brick environment, surrounded by asphalt, concrete, and clangor, had erupted biologically as though to save the sensuous flesh of their inheritance from a macadamization of the psyche, save the blank city wall of their unfed brain by painting the wall over with giant trees and petty plants of a tropical rain-forest, and like such a jungle, every plant large and small spoke to one another, lived in profusion and harmony of a forest."
