Incandescent lights are super! Yes, they are!

Wandering Light

Garrison Keillor's Writer's Almanac posted a nice tribute to birthday girl Virginia Woolf (she was born on January 25, 1882) citing this passage of hers:

We all indulge in the strange, pleasant process called thinking, but when it comes to saying ... what we think, then how little we are able to convey! The phantom is through the mind and out of the window before we can lay salt on its tail, or slowly sinking and returning to the profound darkness which it has lit up momentarily with a wandering light.
