Quasi-analogue clockwork

Digital watches with displays consisting of numbers only have lost much of their popularity over the last few years. They are now outnumbered by traditional dials with hour and minute hands actuated by a digitally controlled stepper motor. These watches (and clocks) are the best of both worlds because they have an analogue readout with digital control. The LED clock described in this article is based on the same principle, only there are no moving parts at all.
