My Rotoball Idea

So, basically, today we were showed some nice flash concept of an animation. The focus of the animation was creation of a changing "ball" which did not have any restrictions, but to simply interact with the ball. While I was watching this animations, it occurred to me to do some animation regarding something I like, like video games. The problem with the subject, is that is hard to involve a ball while I am playing. I consider this as a big challenge, but I am open for some difficult challenge. Perhaps, after I do this I will know gain some more experience with flash. In conclusion, I am awaiting to figure out who I am going to make the animation deal work out.
