The ONLY one that’s accurate to the Local Time’s Second. All the other ones are only accurate every five minutes. My Fibonacci Clock uses Three Stacked Levels: The Top Level for the Hour, The Middle Level for the Minute & The Bottom Level for the Second. The Top Level has a external square as a PM indicator. The Middle & Lower Levels each have Four external small squares, each which represent increments of 12: 12, 24, 36, & 48. Once a Fibonacci Rectangle reaches a count of 12, it is cleared, and an appropriate external square is updated. Once a Fibonacci Rectangle reaches a count of 12 AND its external 48 square is also colored, that complete level is cleared, and the next higher level is updated. The link above leads to an uploaded zip file that contains the single JavaScript html, the source code saved as a text file, and a PDF with documentation. Since the display is flex expandable to fit any monitor's screen size, the program makes an excellent "nerdy" screensaver on a computer with a clickable shortcut for it on the desktop to load and run when idle.
