Nice job. The Pong one was a nice touch where the ball traveled within a second from each paddle. I also enjoyed the interactive fiction game clock. It doesn’t really have much to do with time, but I still appreciated how the little descriptions changed over time.

Looking through all of these, you can definitely start to see patterns in themes. For example, it’s a clock but in a different language. Or it’s a clock but wrapped around a classic game - I think I saw Nine Men's Morris, Mancala and Scrabble among others.

I made the Chamber of Clocks [1] about half a year back which is a set of 12 different clockwork visualizations that I came up with so I was curious (and a bit trepidatious) when I saw this post. I was rather relieved to see that Opus 5.5 left to its own devices didn't create a single thing that resembled any of the ones I came up with.

The closest might be the Ctesibian water clock, but mine is significantly more elaborate, modeled as a 3D physical water wheel.

There’s another one I’ve seen floating around on HN — the Triclock [2] — which is particularly nice as well and worth checking out!
