title: jQuery Masonry from bottom up
body: <p>Does anyone know how to make jQuery masonry stack from the bottom up? I wrote some rudimentary JS to stack things from bottom up but it couldn't do masonryish stuff like stacking the next brick on the shortest column and bricks that span multiple columns. Since I'm not good with Math, looking at the source code just makes me dizzy.</p>
