Storms can be symbolic.
Anyways, the little 'storm cloud' above is actually quite cute and not at all threatening. It was created by Marc Simon Frei. You can see more of his Tesla coil work HERE.
Anyways, I do love clouds, and lightning is interesting as long as it doesn't strike me....why does it have to make such a terrifying sound when it does strike, though? Maybe, if when it struck it made music......
Storm Cloud Looks Like Michael Jackson
