Wow, this is impressive!

Here are some notions of physic (dont worry no one in holywood know them:

- laser are just like a light but all the rays are going in a straight and paralel (sp?) line, thus it is way more powerfull than a simple flash light.
- laser dont 'glow'. Actually, they do but its because they arent perfect, they colide with particles in the air that make the ray bounce away from its original path.

Of course, this is totaly not relevant to your movie, I just wanted to point it out... You can do as you please.

But on the visual aspect of thing I would reduce the glow a bit and maybe use the traditional color of laser: red.

About the animation: wow! Very cool and realistic, I cant wait to see a few of them at the same time.
