World Watch
12 zones, 13 faces and 14 hands telling time | |
Though probably best suited for an airport terminal or international headquarters, this fanciful clock would also look good on an office wall or as a wristwatch. Its central clock face has two hands to show the minutes and seconds.
Encircling it are twelve smaller clock faces to display the hour,
around the world. The hour faces are joined to spokes radiating from behind the large face and they orbit it like cabins on a Ferris wheel. The end of each spoke acts as an hour hand pointing to the correct local time on its clock face.
As the ring of clocks slowly turns clockwise, the hour hands display the march of time across the hour discs that are weighted to stay vertical. An alternating text display on each face shows the name of a major city, weekday and ‘AM’ or ‘PM’. Cities such as Adelaide and Katmandu with local times that differ by 30 and 15 minutes respectively from the time zone norm would not be included.

I don't really know anything about Roman numerals but is XLV really 45? shouldn't it just be LV (50 -5)? |
|
| |
From the link: 'However, proper Roman numbers are subject to the following restrictions about the applicability of the subtractive principle. ... |
|
| |
The subtractive principle (a subtrahend preceding a minuend) may apply: |
|
| |
Only to a numeral (the subtrahend) which is a power of ten (I, X or C).
For example, "VL" is not a valid representation of 45 (XLV is correct).' |
|
| |
If the spokes moved round at twice the right speed for this idea to work, then the clock faces on the ends of the spokes could be replaced by real clocks and the idea would still work. |
|
| |
I agree (clockworks instead of gravity can keep the faces vertical) except for the speed, otherwise in six hours the Sydney clock would be back at the top upside down. |
|

I was expecting a view from space, with the continents moving around to show which millenium we're in. |
