Context Free (and the command-line tool cfdg) is a digital art program that takes a description of an image and generates the image (as a bitmap, vector image, or movie). The description is in the form of a context free grammar and is called a cfdg file (aka context free design grammar). The typical use of a context free grammar is to analyze a sentence of symbols to see if they can reduce to some root symbol. Context Free turns this around by starting with a root symbol/shape (called the startshape) and using the grammar rules to elaborate this into a sentence of symbols/shapes (squares, circles, triangles, fills, or user-defined).
