This is a great idea and very creative by user u/radekp88

12 data fields, each representing 5 minutes incremental around the clock.

The red one on the 12 clock position is the current minute.

Then every 30 degree has following values/expression:

angle: [0, 30, 60, 90, ..., 330]
offset: [5/60, 10/60, 15/60, ..., 55/60]
x:  100 * Math.cos((angle - 90) * Math.PI / 180)
y:  100 * Math.sin((angle - 90) * Math.PI / 180)
