Very interesting. Only thing that I see is that it's difficult to tell a difference between an 8 and a 9. Like I could see how it was different on the physical clock as it changes, but if I were to just look at it on its own, it would be hard to tell without literally trying to count the sides. I'd probably just make up some symbol for those. but otherwise very cool!

Grouping the dots would probably help.

Ignoring the orientation constraint, one easy way to tell is that one has a flat line on the bottom and the other doesn't.
