Graphics advice

I’m working on a space game that involves shields that need to be represented visually. I prototyped them with lines but that lacks visual appeal. I’m looking for something more neon/luminous. Any advice on how to create such an effect without resorting to an external module like Devil Squid’s Neon Shapes? 

Is there a particular generator effect that works well for this? Or a looping transition?

Thanks in advance.

What I did in Omniblaster, way back when was to create several semi-transparent images that went around my ship. I had 5 of them in various states of fullness stacked on top of each other. Each hit I took a way one of the shields, so as play progressed the player could see visually they were getting weaker and weaker. As they got power ups or over time as they recharged, I would add the next layer back

Thanks, Rob. I’ve been experimenting with something similar by varying the alpha of the shield image (now a thin gradient rectangle rather than a line, because it looks better).
