Lightning

A scene with a long cloud along the top with sections that are black, gray, and purple, and a bunch of yellow lightning bolts coming down from them. There is also a yellow circle in the middle.

I think the yellow circle in the middle is supposed to be ball lightning, on a brown fence. When I was young, we had a CD-ROM with an encyclopedia on it (I think Encyclopedia Britannica), and it had an article on ball lightning, which I remember liking, and it had a link to a video, but it was just a video about lightning in general, which I found disappointing. I didn't know at that point it was as elusive as it is.

Also, dark clouds totally look purple sometimes (although generally just clouds in the distance, not straight overhead like these are… although it is weird that the blue sky is showing through).
