Recently, I was looking for a good WordPress theme framework. While reading an article on sitepoint I came to know about this wonderful framework. It is like genesis and it is oriented for developers (coders). It have lot of hooks and filter which help to develop theme. It uses http://getuikit.com front-end framework (I prefer bootstrap or foundation). This framework is developed by Thierry Muller, One of the great developer in WordPress community. Have a look http://www.getbeans.io I have just start learning its documentation and its seems to have lot of great and modern features. I am sure if like genesis, you will also like this framework.
