Love the gear thing as well..
Not sure if this will help or hurt, but I gathered a designs from DeviantArt...
I in no way plan on copying, just some inspirations and ideas..
Love the idea with the gear as the container, utilizing hotspots will free up many design constraints that happen from Windows Native GUI..

mindseye.
EDIT:
More inspiration could be found searching for game GUI etc. im sure.
