The Lazer Cutter Is a Great Idea, Right?

The lazer cutter is a robot attached to the side of a building. The depth of field is quite tight, so you can't really do much with it. It originates in a big old tube full of c o two, and then it bounces to a couple of mirrors,. And then right as it angles down to go to your piece of wood, it goes through a lens that focuses it down to a very small point. If it's an inch out of place, it's not even going to make a mark.
