Dozen Clock
Read full descriptionHide full description
Dozen Clock shows the time in a different way than other clocks and watches. In digital and analog format, too. It enables the user to have a tricky but still precise display of time enabling perhaps new ideas to root and grow. Released currently exclusively for Apple products, the application is able to display the date also in the format according to the Japanese calendar. INSTRUCTIONS: The biggest rectangle in the middle shows the minutes ( numbers outside the circle ). The small rectangle in the middle shows the hour ( darker numbers inside the circle ). The small red rectangle in the middle shows the seconds ( no numbers since it functions like in normal clocks ). "Think different." - Steve Jobs
