We often check our clocks when we have to be busy.In addition to the function of telling the time,
I want to make a watch for when we are busy.We can take a break while looking at images that change over time.Also, even if it is the same time,the images changedepending on when / how long you check the time.

So you are ‘giving’ the time to clock, too.
