Designed by Seungkyun Woo & Junyi Heo, the Leaf was inspired by our good friend, photosynthesis.  The concept is simple, and genius.  Where ever you are outdoors, your cell phone is charging.  The Leaf contains solar cells on its front panel, allowing the sun to keep the battery at full levels on a consistent basis.  And of course, if it happens to be a dark and gloomy day, you can use a trusty electric source to charge the phone in a more traditional way.  The phone itself is very basic; it does calls, messages, and that’s it, really.  And yes, it is made of flexible materials so it can bend to your wrist.  However, the main objective of the phone does not lie in its functionality; its aim is to “remind people that they can contribute to energy efficiency.”
