Drupal 7 theme similar to Wordpress Twenty Fourteen theme? I'm looking for a Drupal 7 theme similar to the wordpress theme Twenty Fourteen. The main factors that I would like to find in a drupal theme are 


the image grid for posts similar to the grid pictured on the theme page 
the menu locked into the side
responsive


I was hoping to find something with as little modification needed as possible, but I'm not opposed to creating a subtheme and doing some customization. I tried searching some drupal theme repositories like the offerings available on themeforest and template monster but I haven't found anything that caught my eye.
You're going to find Drupal is pretty limited on well made pre-built themes. If you're looking for a good grid system, NineSixty and Boostrap provide a good base to build upon. As far as menu settings and post output, this is typically custom to each site. The post output, for instance, would rely on a custom content type and View to display this information.
