Mirror Depicts the Level of Water Consumed

The mirror presented here is anything but ordinary, being able toillustrate the amount of water a person uses throughout the day, month and year. The rims of the mirror are enriched with LED colored lights. These LEDs show the amount of water that runs through the sink. The mirror was designed by Jin Kim.

With this device you can monitor your water consumption. You can also
set the amount of water you wish to use during the day, month or year
and the device will automatically turn the water off as soon as the level
of water consumed exceeds the pre-set level.
The circle mirror does not only show the overall amount of water used,
but the consumption level of cool and warm water as well. It also
features different icons illustrating helpless children and
representatives of the animal world with numbers depicting their struggles.
These icons are shown at the 4 poles of the glass.
