This is a template I made a while ago and just brought into Concrete 5! 
ALSO!! Try looking at Simply Grunge  

Features/Benefits:

** Responsive Layout
** Page Type for ChadStrats ProBlog
** Validating HTML5 Markup
** 3 blocks come with the package
** Styled drop down navigation 
** Print Style Sheet

** Oh, and it's pretty.

Blocks included with this theme: 

** Vignette - easily add an image and "power phrase" to your home page as seen on the demo site: http://simply.isitvivid.com/simply-clean 
** Simple CTA - Add a Call to Action to your site.
** V-Card footer address - This is a v-card block to shape up your footer address in vcard format for different web apps and for google local to love on.

This was built and tested in 5.4, but there should be no reason why it wouldn't work in lower versions.

If there's any glitches you see, feel free to contact me directly. :)
