I've been doing searching. There are some possibilities, although I think I'm looking at a substantial learning curve for what ever I end up using.
Since I lack the funds to build a real prototype, the next best thing is to show somebody a simulation right?
People just look at my math, and then say I'd like to see one work before anything else. So what else have I to do except build a simulation model.
I found an app called Step that looks like it will be fairly easy with which to get going. I just hope it has the capability to do what I want.
