Trefoil

The hour and seconds scales are trefoils.

How to read

There are no hands. Each scale is a line that is thick from the top up to the current value, and thin after it.

    Hours

    The outer trefoil is the hour scale. Each leaf holds four hours: the tips are 12, 4 and 8, the valleys between them 2, 6 and 10, and every hour is an equal length along the line. The green line is thick from 12 up to the hour: at 10:09 it has just passed the valley at 10.

    Minutes

    The circle around the trefoil is the minute scale. The orange line is thick from the top up to the minute: at 10:09 it has passed the tick at 5 and is nearing 10.

    Seconds

    The inner trefoil follows the outer one and is the seconds scale. The blue line goes round it once a minute, five seconds to each hour mark: at :35 it has passed the bottom valley (:30) and is on its way to the left tip (:40).

Rules it breaks

Compared with the classic clock.

  • R1
    The classic clock

    The scale runs round a circle.

    Here →The hour and seconds scales are trefoils, not circles. Each leaf holds four hours, so the day falls into parts of equal length.

  • R2
    The classic clock

    A hand points to the value on the scale.

    Here →No hand points at the value. The line of each scale is thick from the top up to the current value, and thin after it.

Same as the classic clock

  • 12 at the top
  • Clockwise
  • 12-hour cycle
  • Round minute scale

Story

I was experimenting with the shape of the hour scale. I wanted to split the day into a few parts of equal length, to help you sense which part of the day you are in.

I was also curious whether it works to show the current value with line thickness instead of a classic hand.
