This is a fast experiment on Context Free Art implementation in Quartz Composer.
A few month ago I started to experiment with Context Free Art (here are some screenshots from flickr). Now I tried to implement a QC plugin that renders a sequence of rules, using random function to choose what rule of the grammar evaluate each time.
Rules evaluation happen in the start() method of the plugin, so every frame you have only to draw the vertices evaluated, not the entire grammar.
