Corky is the little brown mouse that could. It was a finalist in the Greener Gadgets Design Competition and was created by designer Adele Peters. Corky does not use disposable batteries and gathers kinetic energy from the movements of its scroll wheel.
This little brown mouse has a cork shell and is made from 100% recycled plastic components. Using piezoelectric elements Corky can generate energy without much effort. Use this mouse regularly and it will keep on clicking.
