General Question about these sorts of graphics

[Mousse420]

I am Leading the development of an independently produced computer game. The game is very futuristic and I wanted to have a primary weapon system that dynamically combines different colored and shaped beams, in much the same way that I have seen screensavers and music visualizers do. I will eventually want to recruit someone just for the purpose of creating these weapon effects, but I want to get a better idea of what I'm actually asking them to do and where to look for someone who can do it.
