Shake MP3 Player by Kenneth Tay
"The Shake MP3 player by Kenneth Tay makes use of kinetic energy to keep the batteries charges, similar to modern timepieces. With the hold button switched on, jerk it a few times to get the juice. Yea I just said that. Conversely if you leave the hold switch off, the jerking shaking pauses/plays music."
