Simple binary design for nerds.
Only the time in tens and ones in 3 groups for hours, minutes and seconds.
And a small symbol when battery is nearly empty.

Creating binary display with more than 4 bits isn't possible because the api only allows separated pictures for tens and ones of hours, minutes and seconds.

At the moment the Cor sometimes (every few seconds) skips a second, the display seems not to redraw exactly once per second.

No further modifications planned.
