Context Free (software)
Generative art made by Leonel Cunha with Context Free :
Context Free is a program that generates images from written instructions called a grammar. The program follows the instructions in a few seconds to create images that can contain millions of shapes.
Chris Coyne created a small language for design grammars called CFDG. These grammars are sets of non-deterministic rules to produce images. The images are surprisingly beautiful, often from very simple grammars. Context Free is a full graphical environment for editing, rendering, and exploring CFDG design grammars.
