Digimech Clock by Duncan Schotton

You know a cool piece of design when you see it - and this is definitely one cool item. The Digimech Clock combines the idea of a digital display with an analog, mechanical system. The negatives of the numbers are printed on long slides and only when they are perfectly aligned with the display they show the correct number. It all works with a system of little motors and counterweights. When the sliders have reached their highest pointt hey automatically drop down and the process starts all over again.
