It's the Bat-Light, Boywonder!

God, it's scary to know that someone else is as warped as me. That was
*my* first thought, too!

So what, exactly, causes this phenomenon?

From http://wcco.com/weathernews/local_story_337230308.html:
Light pillars are formed when ice crystals in the sky refract the light from
ground light sources. When enough of the crystals align, pillars of light
appear in the sky.
