Summary Block used as a Pinterest-style Blog
This makes a mosaic grid effect, a lot like the layout you see on Pinterest. If you don't like how your template's main Blog page looks, you can use a Summary Block on a normal page as a replacement. Just remember that unlike the main Blog page that comes with your template, a Summary Block doesn't have navigation to your older posts at the bottom.
I've added some custom CSS to create the borders and drop-shadows.
