Calidu Rocking Horse

German industrial designer Gunther Schunn decided the best way to teach children about the environment was to intertwine it with play.  This rocking horse's oscillating motion powers an OLED lamp reminding kids how much work it takes to produce energy. OK and if they don't care at all about the energy component, the rocking horse is bound to be fun and looks great next to your sofa. More photos after the break.
