AFT (Almost Free Text) is a document preparation system. It is mostly free form, meaning that there is little intrusive markup; AFT source documents look a lot like plain old ASCII text. It has a few rules for structuring your document, more to do with formatting your text than embedding lots of commands, and it produces all types of output (HTML, XHTML, LaTeX, roll-your-own XML, etc.). All that needs to be done is to edit a rule file. You can even customize your own rule files for specialized output.
ASAPlate separates PHP source code from templates. The library is based on FastTemplate, but the project has a different philosophy. It is easy to learn and use. There's no need to especify in the source code which templates will be found in the template files. Template files can be edited with any WYSIWYG editor, can be dynamic, and are recursively parsed.
ASCIIweb is a text-to-HTML formatting system that uses the 'pre' tag to create ASCII art Web pages, either on the fly or for static retrieval. It has a simple and flexible module system that also allows you to integrate shell scripts and practically any text output into your Web pages. It will also parse and include live Apache-style directory listings into your pages, giving you a creative and sharp looking way to make files available to your users. It looks just as good in Lynx as it does in Firefox.

Alphabet Soup is a project which attempts to determine a number of things about the shapes of letters in several different writing systems. First, it hypothesizes a set of basic building blocks that all letters are built up from. Second, it hypothesizes a set of rules, a grammar or syntax, which defines how those pieces combine to make different letters. It can generate individual letters, randomize letters in an input string to create weird but readable text, or generate random strings of symbols.
