zena is a Ruby on Rails  CMS (content managment system) with a focus on usability, ease of customization and web 2.0 goodness (application like behaviour).

You can watch the videos to get a first idea.

With zena you can create a web site and easily update it’s content without taking the phone to reach your webmaster. But unlike most other tools, there is no admin interface in zena. You add, remove and update the content where you and your users see it: on the page.

To have a better view on zena, you can read the full list of features or dive directly into the documentation. If you just want to follow the development of zena, you can read the blog.
