Rubricks is a new Ruby on Rails based CMS. The demo looks pretty good. For bad luck it’s crashing my Firefox browser everytime I tryed it :( Working with Safari.

The english site is still not fully functional (the registration at least working). If you decide to go with the japanese site , the registration is different for the both sites, so you cannot try both of them with one registration. Heavy Ajax usage – be sure your browser have JS enabled.

2006/04/02 Update: And another Rails-base CMS Eribium (the demo is also available)
