Animal is a static website/blog generator written in PHP. It lives on the server and has an interface similar to most database backed blog engines use.
Animal was written as a workaround to a problem I had at work. We had a tightly locked down server, not allowed access to a database, and my task was to bolt on a blog to an already existing site. So I wrote Animal. It writes static files to the server, updates existing files, and uses Apache htaccess and htpasswd for administration. It's a fun tool to use if you want a fast, static site, want to play with some PHP, or have a situation where you can't use a traditional blogging or CMS engine.
