Scots with Lasers?

I like lasers as much as the next guy, but it's hard to get super excited about this. I like the idea of 3-D models made from photographs better than of lasers, although I see how it might be useful, and of course any time we get closer to actually recreating star trek technology, I'm for it. Obviously lasers are much more precise and create better accuracy for surveying a building/object, but I don't think this is really new technology.
