Remember my new "sun tunnel?" Turns out it has a bonus entertainment value. It's a wild light show in a thunderstorm. If I had a real internet connection, I'd add a video. But use your imagination. Don't forget, it's not just a hole in the ceiling. It has a lens on top. It was GREAT!
By the way, last week I noticed that a house near my office was having a sun tunnel just like mine installed.
