And along with Trond's comment is the fact that this looks exactly how fast time seems to fly the older I get. I am sure the pendulum of life is frantically swinging as depicted in your photo.
The movement of a pendulum is somewhat depressing. As I know that time is passing, and remaining seconds, minutes, days and years is limited. Well, it makes you think!
Great find. I must admit I was thinking of something along these lines but couldn't find the right subject. In any case it's a cool demonstration of the change in acceleration of the pendulum at the end of the arc. Barry
