Too cool! Thanks,

If you've never seen them, they are like a ground based localized version
of
the Northern Lights - only they're all around you.

It looks like 1,000 search lights all pointing straight up to the heavens.
The pictures on the TV website DO NOT do the view justice. And colors too.
Simply beautiful.

Why, on nights like these, the ground source light doesn't diffuse more as
it goes up is beyond me - as you can see in the links, pillars of light
are
formed ...somehow??

In my lifetime I've seen light pillars fill the night sky - twice now.

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?

I've seen the local skating rink light pillars as a kid - I remember those.
But to have the whole night sky filled with what look the Northern Lights,
along with rows upon rows of colorful light pillars, in any direction you
look - that's pretty rare ...for me anyway.

Cool! I had never heard of this type of phenomena before. I'm guessing
that it takes pretty cold, and relatively rare conditions.

In Ohio, (where I grew up) when it was snowing, the ceilings were usually
low, and the temps were usually not far below freezing. Not the right
conditions, I suppose.

Ice crystals and snow are totally different. In Northern IL today we had
clear blue skies with ice crystals falling. You don't see snow in those
conditions. You typically see ice crystals when it is very clear and very
cold.

Not the right
conditions, I suppose.

OK, I'll bite. What is the connection of the light pillars to Tron?

Teleportation/communication links, ie. I/O Towers. They looked like
"light pillars"...

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.
