image generator based on context-free grammars
Context Free is a program that produces images based on context-free grammars. These grammars are sets of non-deterministic rules that determine what an image should look like. The resulting images often resemble a mix of spirograph drawings, fractals and abstract art. . Context Free can generate images with millions of shapes, in PNG (up to 100 megapixels) or SVG format. It can also produce animations. Many example images are included.
