Provides 'Masonry' style layouts as an option for rendering the contents of panel panes. Masonry rendering will re-pack panes in your panel to minimize vertical space and provide column-like appearance while the items are still in natural (horizontal) order on the page. With "Responsive" layouts happening everywhere, the Panels approach of locking everything into a grid can provide a bit of a dilemma, because your column count is pretty static. But the Panels approach of letting an editor drop elements into a page in certain zones still works well in some cases. Using this module, you may be able to get the best of both worlds.
