Korean company 11+ has come out with an ingenious, and good looking, World Clock. It lets you adjust the time zone by simply rolling its cylindrical body to the correct time zone. The body has 24 different cities listed, and when you roll the clock so that your preferred city is at the top (12 o’clock), the rolling mechanism instantly adjusts the hour hand to the selected city.
