Clocks For Immigrants
the idea is a clock that has two (or more) hour hands so you know the time of different countries or places simultaneously.
I merge two clocks for different time zones into one clock, using the fact that minutes hand and how to count time are same all over the world, only hour hand is different.
With this idea, immigrants can make their own clocks that have two hour hand, one for the time of foreign country they live, another for their native country.
For example, for me, I made a clock that one hour hand points the time of NY where I currently live and another hour hand points the time of Japan, my native country.
