At 100 Acres Manor in Pittsburgh PA they use them and they look awesome. If im not mistaken they're located somewhere behind their facade and it shines thru every few seconds, you can see them for miles and they give a great look to the place. Mixed with tons of fog pumping out everywhere its a nice effect.
