[nzegwavy] Antialiased continuous clock animation

Create a simple animation of a analog clock with continuously sweeping clock hands. Continuously sweeping hands are seen in AC powered analog clocks in the real world: the second hand (and the minute and hour hands) moves continuously as opposed to ticking once a second as seen in other mechanical or battery powered watches and clocks.

The animation should update fast enough for the eye to perceive as continuous.

Use antialiasing. As the hands move, the antialiasing "gray" pixels slowly change in brightness.

An idea for a modern screensaver.
