Dancepants Kinetic Music Player

Want to go green? Cross your fingers that the Dancepants Kinetic Music Player concept would be realized in the future then. This device actually forces you to work for your tunes, as it will convert whatever kinetic energy garnered from running or dancing into electricity for your MP3 player. The high-tech leggings will allow you to enjoy the fruits of your labor, and in a strange way forces you to keep on moving if you want to tune in to your playlist. Only extremely motivated people need apply.
