3d navigation through content
Like 3d visualizations? Well you must have a look at a site which uses 3d visualization for their content.
Found this site and liked it very much. It is an example about how to navigate through content in 3d. I think we will see more and more of these initiative and in the near future we will navigate through content in a 3d way. How this may look like just see the 3d navigation engine.
