At this point it'd be worth creating an old-school webring [1] for all the HN clock enthusiasts. :)
The clock at: https://clocks.dev/clock/lock-screen
is kind of similar to one of my clocks: the Filling Digit clock [2], which fills the hollow digits with water from the bottom up to represent the seconds in a minute:
Another one that made the rounds here on HN was "Alphabetical Clock" [3] which is pretty amusing.
