Watch the center of the screen for the 'dancing cloud'.
From meteorologist, Joel Gratz:
The answer lies in this: ice crystals, especially long needles, tend to become aligned with the ambient electric field.
So what you are seeing is sunlight reflecting off ice crystal faces that are constantly being oriented by the developing electric field just above the [cumulonimbus] top. Then there is a discharge in the cloud, and the field collapses momentarily, and the crystals begin to realign again. Then this just keeps happening over and over.

Someone else saw that and thought, 'space aliens!'
Yes, in days of yore such a strange sight would be taken as some kind of omen or message from the gods!
I was thinking the same as the others. That would have been a "sign" if someone say that in ancient times.
wow never seen anything like that
I have never seen anything like that either, must be fascinating to watch!
