A fixed set of self-imposed constraints (one font, one image, one palette) speeds generative iteration

Rodenbröker’s ‘magic formula’ for programming posters is a deliberate set of strict rules — a single fixed canvas format, a black background, one typeface, one public-domain image, a centered composition, and a black/white (optionally color) palette. The point of the constraints is not aesthetic dogma but speed: by removing most choices up front, creative decisions during a session collapse to a few parameters, so you can iterate and explore variations quickly instead of re-deciding structure each time. This is a general creative-coding principle — narrowing the design space produces a recognizable personal aesthetic and faster output.

Examples

Always start: size(900,1100); black background; one PGraphics poster surface; one font; one loaded image centered. From that fixed scaffold, only the image, text, and wave parameters vary between posters.

Assessment

Explain how self-imposed constraints can speed up (not restrict) a generative-art workflow, and name three constraints in Rodenbröker’s poster formula.
