By writing code for generative art you are writing a story. A story starts with a single premise, then each sentence is written to support and stretch it. The plot’s skeleton must be scaffolded, the characters known, and then each line carefully shaped, unfurling to the reader (and often to the writer) an understanding that builds and broadens, with tension and surprise but without trickery. This, then that. If, then, else. Imagination following pathways of logic.
