We've been working for quite a bit and developed a custom WordPress theme for our Rio de Janiero Guide.
It implements the Gridster js library to achieve a well organized presentation in the homepage and in the category/tag pages.
Navigation is almost fully ajaxed.
Fullscreen post backgrounds in posts give a lot of character to the site.
A special feature allows the user to build and download a list of posts in PDF.
We are still doing the latest fixes; we might consider to make the theme downloadable for free. I would like know if you like this site concept - and what do you thing - while enjoying some nice views of Rio de Janeiro.
