Domino Placer

This is a cool little project I've seen. The project consists of a car with a slot for dominoes. As the car drives, an arm pushes the dominoes out in a straight line with correct spacing. This allows you to quickly load up and set the dominoes. I figure Lego would be a great medium for this project and it will give me a good opportunity to work on Lego mechanisms.
