This theme has been the personal project of P.J. Onori with the gracious help of Jon Christopher. The theme was designed to provide a lightweight theme focused on the reading experience. Frank consists of the parent theme (/frank) and a child theme (/somerandomdude) which is what I use at somerandomdude.com
Frank has several different layouts to choose from for your home page. Most layouts let you specify the number of posts to show and from what categories. Templates can be stacked by any amount and order to give you the structure you need. Additionally, there are plenty of well-placed widgets that will give you that extra level of customization.
Frank uses a subset of Foundation to provide a responsive layout for desktops, tablets and phones. Add this to the theme's small footprint and you have a mobile-optimized blog.
This theme is 100% open source and developer friendly. The parent theme (/frank) is under the GNU Public License and the child theme (/somerandomdude) directory is under the Creative Commons Attribution-ShareAlike 3.0 Unported License.
There is always more to do, but I need help. This project relies on community support, so if you find this theme helpful, please contribute.
