Button animation which effects other elements on the stage?

Hi all i came across this website by andy biggs and have seen his work and was very impressed.
Just a query i an aware of the process of animating a button within flash however i haven't touched upon the areas of being able to effect other elements on the stage when you rollover a button?

Any ideas will be greatly appreciated

This isn't exactly the same, however the principles are. It should give you enough info to where you can build a custom one for yourself.
