Infinitas is a free open source CakePHP powered CMS that I started around 2009. A few other developers have joing the project and it potts along slowly. The current thoughts are to migrate Infinitas to CakePHP 2.x which will give a nice speed boost and lower the code base. CakePHP 2.x provides a lot more plugin functionality that Infinitas aimed to provide now that 2.x is out.
