It starts to occur to me that I don't actually want an instance, I
want the real deal.

It may be a nonsensical statement here (good to know), but in the 3D
CAD world that I'm used to, which I have been leveraging in my
attempts to understand OOP, there is a distinction between instances
and the source item.
A working knowledge of 3D CAD programs does not translate directly
into the learning of OOP concepts. In a 3D CAD assembly you could have
a master object and multiple instances of that object. In OOP you have
classes, instances, and pointers. Not exactly the same thing. I would
recommend you forget about 3D CAD for a while and concentrate on the
fundamentals of C and Objective-C. Best of luck.
