I still have the WebObjects 4.5.2 (and 4.5.1 I think) boxes somewhere - the last version to support Objective-C on the desktop (that is Windows).
I was really overwhelmed with joy, when I saw how one can add say middle-wheel support to a whole system, without recompiling, or doing some low-level drivers, hacking, etc. - but by just extending it with OO - this is the code I'm talking about - http://www.rubicode.com/Software/Legacy.html#RCWinMouseWheel
It's probably not safe to do things like this nowadays (security), but I still like the whole idea of one being able to replace classes with others without recompiling everything from scratch.
