Hmm, interesting. Now that I've thought about this more I think it might be neat if there's like a visible current wave flowing through the tubes. As for your concept, Hamneggs, it reminds me more of something you'd maybe see in the special stages. I'm sure it's probably just the colors and glowyness to it, though. Perhaps you could try removing some of the glowyness and add some of the aforementioned current waves into it and animate that.
