Getting Camera to follow falling Dominoes

Hi!

Im doing a game in Unity where the user is allowed to place down dominoes and knock them over. When the player does this I want a camera that follows the dominoes as they are falling down, however im not exactly sure how to do this?

Maybe do the script which will have variable (most likely game object or transform) that will be changed by each game object (domino) OnCollisionEnter() will bring you the collider and let you run the function that goes from one piece of domino to another.
