This clock basically displays the rightish time on your computerscreen. The idea is for how the program behind it tells time.
Your computer is linked to all the stuff in your house. It Times exactly:
When you go to the toilet.
When you make coffee.
When you turn the lights on/off.
When
you turn tv/hifi-set/computer on/off.
When you use electric toothbrush/shaver.
When you leave/enter the house.
When doorbell/telephone rings.
Etc.
Thus it plots the movements through time of all family members. It searches for patterns, it draws conclusions.
It sets the results against normal time for about a month and then it calculates averages. If you brush your teeth every morning between say, 6:30 and 6:45 it is clear that if it detects the activation of the toothbrush it must be 6:37-something. This is not very accurate. But it then correlates this data with the data it gets from the coffee machine and the toilet and shower and front door etc. throughout the days.
One morning the computer is baffled. The toothbrush is not activated at the right time. "What could be wrong? The toilet is used, yes but only briefly. The front door stays closed... Ah the phone rings, but wait! no one answers. What the hell is going on?" the computer says to nobody in particular. "hey, it must be sunday!"
