To read the time, just concentrate on the diagonal lines in each figure and you will see a hidden digit rotated 45 degrees counterclockwise.

On a tap, additional activity information appears at the top and on the bottom the date. Tap again, to hide this.

The colors are configurable.

Screenshot animation runs from 12:30 to 12:40 and then shows extra information and some of the color choices.

Always-on Display compatible – requires Versa 2 with AOD enabled.
