Something similar to f57v.

Ed, I think you might like to read my latest post in my thread, in which I argue that the diagram on You are not allowed to view links. Register or Login to view. is an astronomical clock that bears some resemblance to the Prague clock.

  Thank you for your useful tools

You're welcome..

I did see your post, and the idea of a 4x16 is interesting rather than the traditional 4 x 17 view.. as that gives you 64.. which you could then divide in to 15 minutes sections, but I can't quite make the link with Prague, sorry.. and I can't figure out why 15 mins intervals would be useful.. based on the searches I did, nothing tracked.. but I'm sure you'll expand your post with more info.
