Some of these seem subtly off. For example, on the orange "number field" clock (https://clocks.dev/clock/number-field), you can't distinguish between 12:10 and 10:12. On the "word field" one (https://clocks.dev/clock/word-field), there are "X"es in lieu of unused characters, which makes the emergence of words a lot less mystifying than in the original "word clock" design this is based on. The "temporal exposure" one (https://clocks.dev/clock/temporal-exposure) has weird off-center bands in the blurred area. Etc.

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.

I'd really like an analog watch face for the lock screen of my iPhone.

"Number field" felt like the best spacial representation of a numeric clock (would need to be 24h to be perfect but that's a small tweak)

There are plenty of them in a more linear style, but the 12 columns design really works well IMHO. It's really easy to roughly guess the time at a glance.

What would be the best device to put any of these ones over the desk? And old phone? Maybe an esp32?

I've seen and used some variations of these in my Pebble watch.

They're cool for one day or two. But, in the end, I will always go back to some boring but more information-dense one (with battery charge, weather, heart rate, steps, etc).
