Article: Generative Art: An exploration of meaning
"One might define generative art as art where the main technique of development within a piece or series of pieces is an evolutionary process, like biological or physical evolution, or the evolution of ideas. This might mean that the intent of the work is to make evolution the primary message. Evolution involves a complex process of development with many possible influences. Much of art involves generative processes of development, selection of work for various reasons. These reasons include everything from emotional impact, to beauty, to commercial appeal, to personal fullfillment, to social propaganda, and more."
