Precalculus Project decision OK so I have to do a research paper/presentation on an experiment/project that relates to my precalculus class.  Only problem is that I was given no topics to choose from and I couldn't find any real good ones online.  Can anybody give me some good ideas/topics that I can do? (P.S. if its fun then that's a plus :D)

When i was given a similar choice, i chose this, seemed fun and also pretty useful

will take some effort into building it, but is a good idea nevertheless
