An apparatus for indicating the proper pendulum putting stroke to a golfer with An elongated display device that is positioned on a floor parallel to the stroke path of the practicing golfer, A display device containing multiple microcontroller module sections, each containing visual indicators spaced uniformly along the length of the sections, Each section being responsive to commands from a peripheral computing device to turn on a specific visual indicator, a peripheral computing device such as a personal computer running a computer program which calculates the putting stroke based on desired distance, green speed, and the golfer's personal rhythm rate in beats per minute, A peripheral computing device that after calculating the putting stroke time-position data, commands the display device to turn on and off consecutive visual indicators at a predefined time in such a way as to display a putting stroke path, and show the golfer the proper time-space dynamics to strike a golf ball a desired distance.
