it is possible to follow the ball with the eyes, but it would be necessary to have the pinball at home to be able to work on it.
but the concern is that it would become complicated to plug in and there would be many days of research devellopement to do this kind of program.
this would make the project very expensive and, by experience, it is not valid.
I made with my son who is studying electronics / computer engineering,a mod for the AFM, it's really beautiful and I presented on all pinball show in France, everyone wanted one.
but once the price announced .....
it's a kit consisting of 7 parts, (flying saucer) everything is plug and play, less than an hour to install everything, extraordinary light effect, 10 days of work to assemble a kit when all the parts are ready, it will have took more than 6 months of research to get what we wanted, I never presented it for lack of time and only sold 7 copies, I would sell again but I wanted to do something very extraordinary and thought to be overwhelmed with command, in short not profitable at all.
a link for the curious ^^
morality, we must make the simplest with beautiful effect inovant and like eyes mod scared stiff, I have other ideas just as fabulous.
I'm currently working on a lightsaber for the star wars that should be successful
sorry for this little off topic
