Mouse follow - can this be done?

Please check out this site. At the end of the movie the lighthouse light moves to either button on rollover. Once clicked, it circles around. Can I make this beam of light work the same way by following the mouse?

Oh, the movie may be choppy - it was designed for a CD, not the internet.

Thanks
