Phoca Tre is a Joomla 3 template, so it is responsive in design and suitable for viewing on many different devices. The layout for tablets is especially nice, and the internal pages of each gallery are laid out much in the same way as Pinterest, with commenting and rating available as well.
There is a mosaic view of included images for each gallery's icon on the front page. This template would suit any project where photographs were the main focus, such as travel, design or a photo portfolio.
Version 1.0.0 is available as a free download from Phoca's website.
