    implement a data driven finite state machine framework (build state and transitions described by data given in files).
    Option 1: support various file formats: xml, binary(+editor)
    Option 2: Support states that are state machines them self
    Option 3: graphical output of state machines
    Option 4: graphical input of state machines (should not be possible in your time frame)
    Option 5: Build an execution environment, so the machines can do something meaningful

    That should include a lot of abstraction and polymorphism as well

    Common first polymorphism class would be an "animals" class, where you start with a basic anmial, and then derive classes like cat, dog, fish, parrot, etc.

    That may be too simple, but it's a starting point for learning polymorphism.

    You could make a kd-tree, and use polymorphisms for the nodes. Wiki it, it's can be used for many different things, but I use it for collision detection in my games.

    That's exactly what I was thinking about. That or a Shape class like in Bjarne Stroustrup's book.

    Another variation is a number class that can input/output the number in various forms, e.g. a decimal number, hex number, octal number, binary number, roman number etc. [The decimal, hex, octal and binary are probably best implemented as a common-derived form that has a "base" member that is 10, 16, 8 and 2 respectively - so you have two levels of inheritance].
