Started out as an experimental theme, but I think it works pretty well. It uses jQuery Masonry script to allow for a fluid layout for album and image thumbs. Also, optional, use of Infinite Scroll script which loads subsequent pages directly into the current page. Also has a floating sidebar, which reverts to static if the height is greater than the viewport height.

I appreciate any feedback and cross browser testing. Only tested in Firefox for PC at the moment, so would appreciate feedback on use from other sytems, especially MAC browsers.
