Thanks to our Facilities Manager, Richard McLain, we did an interesting experiment to bring sunlight into the center of one of our libraries through a device called a "sundolier." And thanks to local TV station The Network Douglas County, and producer David Schler, we've got a great piece on Youtube about it. Click the link of this title to see it.
Incidentally, the creator and installer of the sundolier is Jim Walsh. His company, Sunflower Corporation, can be found on the web at www.sunflowerdaylighting.com.
