Often it’s easy to forget to perform in public the energy-saving habits we practice at home. Finnish designer Tima Naskanen designed Change, a tasklight that encourages people to change their environment habit. You insert a coin into the lamp to turn it on, and when you want to turn it off, the lamp will dispense your coin back. How clever! The lamp was designed to be used in public places like libraries, where forgetting to flip the switch is not uncommon.
