Have a look at some of these themes. As the projects are open source you should be able to examine them closely.
Matplotlib documentation is an excellent example I think. They even have a detailed description at documenting matplotlib: dynamically generated figures and inheritance diagrams are their custom extensions to Sphinx I think. Their documentation has a custom logo too.
I would guess that you should be able to download the RST document source for most projects.
