I think we can get some really nice examples going for this.
I want to try to get some sort of electrical wiring one going soon, if I can. Use the lines to connect a battery to a resistor, bulb, etc.
I am sure there are plenty of ideas popping up for testers.
Oh, here is a quick example of an energy beam/pumping effect I was talking about using the dash offset. There is also another one that just uses the star preset for some dazzle. I use four VectorLine objects and it runs smoothly for me.
