Something just occurred to me - does this remind anyone of the electricity produced with a Tesla coil?
There are supposed to be Tesla towers in several places in Texas

no, it certainly doesn't...it looks like electricity, but in an atmosphere composed of different elements than ours. I'm not entirely sure that makes any sense, but that's how it appears to me! It also looks "manmade" in the way that it branches out across the sky. Very, very strange!
