Wouldn't it be nice to have an exposed cable object that sparked, it could even be tweakable for how much sparks and of what colour.
Would be a good oppertunity to show off some particle physics in the way the sparks bounce around off different material.
Idea's are still flooding into myu mind as I write, like making it able to ignite material if the sparks hit it.
Sure you could "Simulate" the sparks with small LEDs but it wouldn;t be the same as actually having a sparking object;
(I was thinking like the detacheable candle flame - you could have a detacheable "frayed wires" spark object).
