Well, lets say you have 4 objects that have selected states & fired no
events on their own.
So there are many different possible combinations for the combined states of
those 4 objects. Each possible combination triggers an entirely seperate
action. Thats a lot of actions to account for.
So its all about detecting the unique combinations, and acting upon them.
Perhaps there really is no truly elegant way of doing this...
