I like it; sounds like a great toy for creative kids and bored adults. Give it a memory function to save particularly appealing results, then string them together into virtuoso Melody Ball compositions, then budding Mozarts can make wonderful music whilst simultaneously bonking their siblings over the head.

During a game of soccer, track the ball with high resolution cameras / telephoto lenses. Decorate the surface of the ball with visual markers. (If you like, they can be infra-red-retroreflective, and you can put coaxial IR strobes on the cameras. That way the appearance of the ball is unchanged for players and spectators).

For some suitable distribution of redundant markers, it should be possible to get the ball's orientation as an uninterrupted, continuous function of time, throughout the game. Map that onto musical notes -- empirically develop a mapping that gives esthetically pleasing notes. //256 nodes// would be one possible mapping. In development, do it offline but, when you've got it working, do it in real time, and offer it as a second, optional audio channel, for those who prefer to watch the game without commentary.
