Just in case you are unaware .... A&E made a four part movie for television called "Longitude" that was based on the book by Dava Sobel. I have never read the book, though I should like to, but I think the movie adaptation is most excellent, and I highly recommend it to anyone who might have the slightest interest!
Meanwhile, that Ball Drop is certainly a wonderful and uncommon accessory, and I do like the history behind it.
