I haven't read this book, but the Cocoa frameworks are a great source of 
inspiration for OO design. Objective-C is pretty lame compared to 
Python, but it's a very nice hybrid from a C perspective; it has dynamic 
method dispatching and a nice object model. Objective-C's and Cocoa's 
philosophy are fairly "pythonic", eg. containment is often preferred 
over inheritance. ObjC is very easy to pick up if you know C and Python, 
which I found is not true of C++ (although I must admit I wasn't really 
motivated to try very hard, erm, at all actually). But then again, I 
only learned a bit of ObjC to help out with the PyObjC project, which 
allows me to use Cocoa from Python.
