Hey Te, I think one of the basic ideas I'm finding is that classes can be used to increase the flexibility and modularity of code. It seems to make sense to me to start thinking about using them when a certain task I want to perform might have a lot of "options." Instead of having to write a function where I pass in a ton of arguments and then do a bunch of argument checking within the function, I can instantiate a class and use its methods to set up the options. I think it makes sense when you are trying to write code that you want to reuse a lot, but in slightly different ways. At least, that's where my [limited] understanding is at.
The code I posted ain't the best example of taking advantage of OOP (in fact, it's quite bad imo)...but I think it's a personal stepping-stone to breaking out of the procedural mindset. It seems like one of those things you just have to work with and try out a lot before it starts to click. One of the things I've found so far is that it can be a bit more work up front to set up a class, so *not* using them unless there's a reason to is half the battle.
