Disk

These are more parts to the puzzle I don't actually have an answer for.

 

The disk is some sort of timekeeping mechanism. I loved the aesthetic of the machine, but I've lost my notes explaining the history and significance of the device.

 

I took these pictures in the Aarhus Clock Museum -- en.wikipedia.org/wiki/The_Old_Town,_Aarhus

 

If anyone from Aarhus, Denmark runs across this photo, do you mind running over to Old Town and telling me what this machine does?

 

Thanks!
