"The way you can tell a fine pendulum is by the reflections of the lights. Do you see the lights? And do you see the colors? All the colors of the spectrum. Can you see the center? The exact center—do you see it? Keep trying. Look at the colors. See how they move. Watch them—they’re brilliant colors. They flash by. Try to find the center. Can you hear anything? The chiming of the hours?"

The pendulum, with its reflective sphere in the middle, is from a haunted grandfather clock we are restoring.
