Libratus is a fully fluid (max-width), responsive theme which looks great on desktop to mobile naturally using mobile first design. It utilizes image and album statisitcs more heavily than other themes, although not required. Home page has a full screen slideshow with optional images to pull (latest, random, popular, etc.). Great theme for a site with a large image collection.
This theme has been abandoned by its original developer and we provide it for archival purposes on our "unsuppported-themes-thirdpary" GitHub repository "as is". We may sometimes roughly update it but cannot promise full compatibility with current ZenphotoCMS releases. Contributions are welcome.
