Thanks for the tips.
I tried out the laser whip thing, but I just couldn't get it to work like I wanted.
Plus, since I added the light effects, the beams looking pretty good.(Although, I must admit that I've been looking at it a lot lately, so my impression may be a little off.... )
Here's the new version. I added a big green dot with some very early capture effect.
I'm working on another approach, though....
