Best Light Pillars Ever!

Or at least that I've ever seen pictures of (thanks, Frank!):

Light pillars are a common sight in Fairbanks during winter. These pillars are originating from the airport runway lights about 1.5 miles from where this photo was taken. Gently rocking plates behave like miniature mirrors that reflect the light towards the observer.

The usual suspects that produce most of the optical phenomena tend to be hexagonally shaped plates and columns. Plates are responsible for the sun dogs, parhelic circles and circumzenith arcs, and the columns are responsible for the 22° and 46° halos as well as the upper and lower tangent arcs. It has been shown that both shapes can generate light pillars.
