I had initially made this concept back in 2014. It was originally an experiment when I was researching MasonryJS for another project where I implemented RefineryCMS. I designed this in the browser on CodePen. I posted the original concept to dribbble https://dribbble.com/shots/1413134-Dive-Tumblr-blog-concept-1

As I looked back at my past work I decided to put this design to use and make it a Tumblr theme. 

Using MasonryJS, the gird adjust to fit the width of the browser window.
