I was lying awake last night, listening to the clock in my room and wondering what time it was.
Having taken my contact lenses out made it difficult to see the clock, let alone read the time.
Today’s invention is therefore a clock whose ticking changes, depending on the time.
If it’s 2 o’clock then one would hear tick,tick,tock. 9 o’clock and it would say tick,tick,tick,tick —tick,tick,tick,tick—tick,tock.
The grouping of ticks into sets of four would make it much easier to perceive accurately the totals involved.
