It's a Joomla looking Content Managment System based on ZF2 (Zend Framework 2). I very like a joomla and ZF, but each of them don't have some features. Joomla don't have a greate base framework and ZF don't have a frendly admin sites as has Joomla. Libra CMS based at ZF2 now. So it can be example of utilizing zf2. If you wish to be involved in project let me know.
