1a. A field of fireflies on a hazy summer night demonstrates a mesmerizing display of effective complexity. While it may appear random and chaotic to the human eye, fireflies exhibit flash patterns unique to their species to communicate and identify one another. When many occupy a single area, I'd liken the complex beauty to that of a symphony orchestra.
1b. Locality, code and morality: When it's a question of "which part" is the actual art, I believe that the code and method of display are both encompassed in the definition. I'd liken the creation of generative art to that of printmaking; as art that is built with the intention of iteration, the process of making the matrix as well as the copies are part of the final result. It is developed under the constraints of that medium, and thrives under those unique demands.
