Yep, life is becoming more and more like the movies. We now have an actual laser that can shoot down incoming projectiles. It's called THEL - Tacical High Energy Laser, or just call it the Nautilus.
I actually was able to find a couple of videos of it at work, one of them is here (Link is directly to video file - Right click if you want to download).
NOW, the only problem that remains is to figure out to "have sharks with frickin laser beams attached to their heads." Yeah Baby.
