RubyCocoa is a lot closer to the Objective C interface than the  
AppleScript one.

Look at the documentation for [NSApplication sharedApplication] -  
this is the method you use to get a reference to the single  
NSApplication object. This happens to be stored in the global  
variable NSApp too for convenience, but I don't think it's accessible  
from Ruby.

So, you'd do:

   app = OSX::NSApplication.sharedApplication

Having said this, I think it's rare that you actually need a  
reference to the application itself - what do you need it for?
