How it works
An N×N grid of clocks has a pin at every interior corner where four clocks meet — (N−1)² pins in total. Click a pin to toggle it UP (blue) or DOWN.
Each wheel always rotates its own corner clock by one hour. Up-pins chain: any clock connected to the corner clock through up-pins rotates with it. Engaged clocks are tinted blue.
Keyboard: 1 2 3 4 toggle the four corner pins.
