caption: The image shows a close up of a clock on a wall with a circular object in the center. The object appears to be a Foucault pendulum, which is a device used to measure the speed of a person's movement. The pendulum is made of metal and has a circular shape with a series of concentric circles radiating out from the center, each circle representing a different time period. The clock is surrounded by a decorative border, adding to the overall aesthetic of the image.
