Word Clock spells out the current time in words on a glowing letter grid, lighting only the letters that make up the current phrase.
The grid holds every word needed for any time, and lights only the ones currently required, so the unlit letters act as camouflage. The whole design depends on the words fitting a fixed rectangle in reading order.
Most word clocks round to five minute intervals because that is how people actually say the time. Nobody says it is seventeen minutes past four, they say quarter past. The imprecision is the point rather than a limitation.
Why it rounds:
Result: The imprecision is the design, not a limitation.
