Simplification and lights

So, I've been simplifying my approach, which is something I should have been doing a long time ago. Anyway, so I'm fleshing out my light source routines. I've got some light sources now that are connected to the agents, and follow the agent around when they move. These are simple fill lights and do not cast shadows; which will be replaced with actual light ray lights when I get to it. I've already got a few different kinds of lights, but I need more. Anyway, here is a screen shot of what it looks like so far. I can tell already that I'll need to deal with the offset problem, trying to get it centered directly on the agent, instead of its top left corner.
