> I’m planning to write something about this too, but this one is more of an art piece: It’s a ticking wall clock that ticks seconds irregularly, but is always accurate to the minute (with its time getting synced over the internet). It has various modes, one mode has variable tick timing, from 500 ms to 1500 ms, which is delightfully infuriating. Another mode ticks imperceptibly more quickly than a second, but then pauses for a second randomly, making the unsuspecting observer question their sanity. Another one races to :59 at double speed and then waits there for thirty seconds, and the last one is simply a normal clock, because all the irregular ticking drives me crazy.

I like this, I've always had a soft spot for interesting clocks, and the first description has a strong nostalgia for me from the Discworld:

> Someone very clever—certainly someone much cleverer than whoever had trained that imp—must have made the clock for the Patrician’s waiting room. It went tick-tock like any other clock. But somehow, and against all usual horological practice, the tick and the tock were irregular. Tick tock tick…and then the merest fraction of a second longer before…tock tick tock…and then a tick a fraction of a second earlier than the mind’s ear was now prepared for. The effect was enough, after ten minutes, to reduce the thinking processes of even the best-prepared to a sort of porridge. The Patrician must have paid the clockmaker quite highly.
