I have a quick question/theory. I'm trying to make a wall-mounted tractor beam that looks like the Gluon gun from Black Mesa Source:

Here's what I have so far (attached)*. I used a pipe entity with a blue fur shader and I intend on adding an illuminate map to it in conjunction with bond1's adaptive bloom shader to give it even more "umph". I then intend on running particles around the entity to give it said effect (because I don't think I can do it with particles alone. If I can, that'd be awesome

).
The question then becomes, how exactly would I do that? I don't quite understand the particle system to begin with, so yeah. Any ideas?
Also, how did they make the emancipation grid-thing in the original video? Sorry if I'm asking stupid questions
*It's one of my worst screenshots, in JPEG nonetheless. I didn't even want to post it in this thread, but I guess I had to. My project looks tons better than this and I'm a little self conscious about my WIP, especially my old work like this.
