Gramo Speakers just might be the perfect outdoor accessory for the audio-inclined. Designed by Pekka Salokannel, the Gramo Speakers are powered by three layers of photovoltaic panels on the surface — allowing you to listen to music plug-less (say while camping, at the beach, on safari, canoeing the Merrimack, etc). The solar panels also charge the built-in battery pack so you can use the speakers after dark. The Gramo speakers can even be bent flat for easy travel, and the volume is adjusted via a soft touch-sensitive control.
