a physical ambient visualization device that displays the amount of energy that is spend in a household. the device consists of 2 parts: a sensor near the home's energy supply that measures how much power is consumed & a wireless display that conveys this information numerically & by brightness level. as colored lights & patterns shine through the material, the device can be used as more than just an energy monitor, for instance as an 'intelligent' mood light in the evenings or a 'last check' when leaving the house. see also power socket visualization & power-aware cord.
