This is really cool, even better than the post, IMO (sorry OP!)
One question: when the second hand resets from 60->0, it visually jerks as the triangle moves. After the smooth movement, gradients, the cool multicolour fill, it feels very odd. Any way of smoothing that one out? Animating the flip back to zero? I do understand it's a one-way line not a circle...
The clock in Lord Vetinari’s anteroom didn’t tick right. Sometimes the tick was just a fraction late, sometimes the tock was early. Occasionally, one or the other didn’t happen at all. This wasn’t really noticeable until you’d been in there for five minutes, by which time small but significant parts of the brain were going crazy.
I love new clock designs, here is my try https://triclock.franzai.com/
