Where does Apple keep the little cloud icon in Mountain Lion? [pics]

Hey, all.

I have an alias in my Documents folder that points to the Mobile Documents folder in my ~/Library folder. The cool part is, when I open that folder from the alias, it says iCloud and shows a little cloud logo. Like this:

I navigated to /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ in order to snag that cool little icon and add it to my alias, but I can't seem to find it. Anyone know where it's buried in the OS? Or is it not?

For now, I'm rockin' what I think is an old school MobileMe Drive icon:

Any help would be greatly appreciated! Thanks!
