Hi Tony -
You write:
Don't forget that hourlines become harder to see as the dial gets higher. 3mm wide looks impossibly clumsy at ground level but just right above 4 metres high!
Do you know of any kind of formula to estimate the proper proportions for seeing high or distant dial lines, letters etc. clearly? I suspect architects, engineers and advertisers (billboards) must have some way of knowing what will be clear to a given eye at a given distance.
