Most of the Blender UI is actually generated through Python files that are part of the distribution. So after reading the API docs I found it most helpful to just dive into the accompanying Python files in the blender.app package. Edit: There's also a ton of plugins for Blender that are all written in Python. Our map exporter actually started as a fork of a simple exporter plugin for another format (I forgot what it was initially). http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts
