Fake Window Lights Up

"Natural Light No Longer Necessary with a Fake Window"
UberReview (November 26, 2007)

"This new fake window is just the thing to brighten up your dreary basement apartment. It makes use of electroluminescent sheets for the light source and you can adjust the intensity of the light by manipulating the shades...."

Odd as it may sound, I think this is a really good idea. A business I went to, decades ago, was in a room with concrete block walls. To make it look better (and less like a bunker) for customers, they had curtains hung in a corner. That created the illusion of a window, which opened the place up.

This follows the same principle, plus it looks like a good source of diffuse light.
