Didn't mean to sound all snooty, I guess I'm just old and jaded. Nothing is new.
What I've wanted to try recently is airbrushing the OSL on the plasma. You can use the airbrush to do all the blending and get a nice look with little work. I haven't tried it myself, but seems easy to just to a little shot where you need the light. Just shoot the light from the plasma gun and presto.
