I think an RC car style servo with the rig attached to it would probably be easiest. It rotates with very simple commands, and just needs power plus one IO pin. They usually have mouthing points and cost <$10 for small ones.
You could also consider using an audio signal if you are writing the app yourself.

>> There's a lot out there. A solenoid is simple but most of the ones I see for sale need you to add a spring yourself and mount them somehow. An RC servo could work. Would a spinning motor with an arm and something at the end be close enough to a "tap"? If you can get away with something that isn't perfectly straight then there are going to be easier options IMHO.
