Twaddle is a text-templating tool. In its simplest use case it replaces placeholders with text from user-provided dictionaries, turning input like 'this is my <noun>' into something like 'this is my apple' or 'this is my camera'. More advanced features include random branches, looping, basic mathematical operations and boolean logic. These functions can all be used recursively, making it this simple tool surprisingly powerful.

Green Ideas is a random sentence generator built on the principles of generative grammar. It applies recursive rewrite rules to turn a root node representing an abstract 'utterance' into progressively more complex grammatical structures.

TextMill is an experiment in using advanced Twaddle features to build a self-consistent procedurally-generated history of a fictional small town. It has not yet received a public release.

TerrainGen is a terrain generation tool. It allows for heightmaps to be generated using a combination of layers, each of which can be generated and weighted separately. Currently it implements Perlin noise and the diamond-square algorithm for layer generation, and a hydraulic erosion modifier.
