Based on a concept originated by Afrotech Mods, Will and I disassembled some old hard drives we had lying around and rigged wires to the circuitry which controlled the motors on the disk arms. The cool thing is that doing this apparently causes the arms of the hard-drives to vibrate at the frequency of any analog signal you pump through the newly attached wires, which in our case would be the music coming out of a 450 watt stereo system I have.
While it is quite quiet, you can definitely hear the music coming from the hard-drive arm, and it is fairly clear. The only problem we found with it was that the bass was rather weak and that the audio sounded a bit tinny. However, after messing around with them for a few minutes, we found a solution.

A fun little project which is definitely doable by just about anyone with an old hard-drive lying around.
