This screensaver shows an analog clock designed according to DIN standard 41090. Four different clock faces (including a numeric dial) are available. The size of the clock, its movement speed and colors are freely adjustable.
The behaviour of clockwork and hands (stepping, moving, bouncing...) may be changed as well. It is even possible to simulate a classic German railway station clock with its typically swinging second hand.
