Context Free is a graphics toy for Mac, Linux, and Windows that executes context-free grammars to produce wonderful recursive and organic looking images. It is similar in spirit to Logo, except that it is less straightforward. I think it would be useful for teaching kids about computer programming and about geometry. It is also terribly addictive. I spent a number of hours last weekend creating the programs for the images below. For more beautiful images, see the Context Free gallery.
