This project by artist Greg Chatonsky generates sound from vibration sensors placed on the exterior of a defective computer hard disk. The amount of vibration is picked up and changed to sound in real-time though a program written in Pure Data on the PC. The sounds (at the link below) are pretty amazing considering their source.
