Well, the whole idea of what I did was that the electricity could be seen flowing into the animated bolt (hence why you also see electricity in the ground tile itself, in what I usually think of as "eye" here). Without that it seems pretty much useless to do it this way (with the electricity in the eye). Only way it might work if you do it the metal way I think if is you make the small bit of electricity in the eye animate/flicker a bit.
