Engineering Systems 2 Project

I gotta build a computer animated model and perhaps of a prototype model of some broad idea that I have no idea what I want to do. :/ God damn, somebody last year modeled the movement of glucose in terms of a diabetic standpoint and another one modeled the tension of ropes on an aerial camera over the University's campus...So I have no idea what I should do.

Model the support a suspension bridge gives, like the tension and how much it moves when cars or people go over it.

Eh, tension does not seem to be interesting enough...Currently my ideas are modeling a basketball or soccer computer game, modeling how wind power could be used to power the University, a model of how terminal diseases such as cancer/HIV/AIDS spread, and a model of the economic view of how water purification could be cheaply done.
