This tutorial from CG Masters came out in August 2014. I found it in November 2014. It is a 13 minute video on using and tweaking the PIE (or radial) menu that came out in Blender 2.72. When the video came out Blender 2.71 was current. The video was a preview of the coming PIE menu and to use that menu you needed to download a daily build of Blender to get it. Now it is included in Blender 2.72, so all you need to do is enable it.
