Justified style theme or module

Hi, I wonder if anyone has created a theme or module that displays images in the 'justified' style as used by Google plus and parts of Flickr.

I guess the fact this style tends to use thumbnails or varying sizes could present an issue, as Gallery has a fixed single thumbnail size

I like the way it has a high impact feel that makes very efficient use of space. Alternatively, a theme that tiles fixed size thumbnails with a very thin, almost invisible margin would be good
