Akelos: Yet Another PHP Framework

Another PHP framework has come to my attention today: Akelos. Its basic claim is that it's a port of Rails to PHP, including adding some "Ruby-like" functionality that PHP can't handle natively. I do wonder why we needed yet another PHP framework when we already have CakePHP, CodeIgniter, Symfony, Zend, PRADO, Solar and probably a hundred others. Seriously, do people create new frameworks for fun?
